Here are a few questions about computers I’ve received recently from people like you, and my answers. I have edited and restated the questions a bit, for readability. This week my mailbox contained questions about whether to buy a smart phone now or wait for the iPhone, boosting the range of a wireless connection, and removing junk programs that come with a new computer.

I am in the market for a new smart phone. Should I wait for the Apple iPhone? When will it be available and when will you review it?

Apple says the iPhone is on track to go on sale in “late June,” and I expect to be able to test it and publish a review around that time. There will also be many other reviews around then that you can consult.

I stand by my earlier advice, which is that people shopping for a smart phone, who can wait until then, and who could imagine shelling out $499–the iPhone’s base price–should wait to read the reviews of Apple’s first phone and take a look at it before making a decision. However, if you need a smart phone now, or can’t imagine spending that much, then you can ignore the hype and buy a BlackBerry, or a Treo, or another competitor.

Three other key factors could also make you reasonably ignore the iPhone. It will lack a physical keyboard, relying on virtual keys that appear on the screen, so if you prefer a real keyboard, the iPhone would be a nonstarter for you. Also, it will only work on the AT&T wireless network (formerly Cingular) in the U.S. So, if you prefer another wireless carrier, forget the iPhone. Finally, it will only operate on a relatively slow network technology, called EDGE, so if you want a smart phone that operates on the fastest cellular networks, the iPhone is the wrong choice, even though it will also include Wi-Fi wireless networking.

The wireless connection to my wife’s Windows XP computer keeps going down. The computer is about 75 feet (but through three walls) from my Dell Truemobile 2300 router. Should I assume I need a better, more powerful router? And, finally, will it also connect to my MacBook Pro laptop?

A more powerful router might help, but wireless reception varies greatly depending on home construction and layout. You might look for a new router that features a technology called MIMO, which I have found in my tests can improve both speed and range. Even with a new router, you might also have to move its location. There are also various boosters and repeaters that can be used, though some of these require more technical expertise to install than most folks have.

One good method for extending the range of a wireless connection is to buy a set of so-called powerline adapters. These carry your network signal over plain old electrical lines, and some models allow you to create a wireless network by plugging a wireless router into such an adapter in a distant room. I described these adapters in more detail in a column you can find at: ptech.allthingsd.com/20060817/powerline-adapters-access.

In my own home, I have used both MIMO routers, and powerline adapters, successfully with mixtures of Windows and Apple Macintosh computers, including the MacBook Pro, and various Dell, Lenovo and Hewlett-Packard laptops.

Can I remove the junk programs that came with my new computer–the ones you call “craplets”–by using the “Add or Remove Programs” control panel in Windows?

Yes, but that is a tedious manual process and may not get them all. Also, in Windows Vista, that control panel has been renamed and is now called “Programs and Features.”

Instead, I would suggest first downloading and running a free program specifically designed to eliminate craplets, the crippled trial programs and advertising come-ons that are now packed into so many new Windows PCs. This program is called “The PC Decrapifier” and can be found at pcdecrapifier.com. If this program misses a few of the junk items you want gone, you can then use the manual method.

Here are a few questions about computers I’ve received recently from people like you, and my answers. I have edited and restated the questions a bit, for readability. This week my mailbox contained questions about accessing financial sites on a nonsecure Internet connection, which cellphones with email capability to take abroad, and what to do about Web sites that don’t work well in Safari.

I am concerned about security on my laptop when traveling and using nonsecure Internet connections available at motels. Is there a way to be secure when accessing my financial Web sites while using a motel’s connection?

You can install a good firewall, and sweep your laptop with security software for spyware and other malicious software that might transmit passwords. And you can make sure you are using antiphishing software. Better yet, you could use a sort of private Internet tunnel, called a Virtual Private Network, or a remote control service, like GoToMyPC, so you are actually using your home PC — remotely — to contact the Web sites involved.

But, the bottom line is that, unless you are on a network that you can control and secure, such as a home or office network, I wouldn’t advise accessing financial accounts online, or performing financial transactions. I wouldn’t trust sensitive online transactions to any public Internet connection, such as those at motels. There are too many people, including other guests, the motel staff, and the people at the company that provides the motel’s Internet service, who could potentially be watching what you are doing.

Is there a cellular phone that can be taken abroad that has a good email capability, for a comfortable price?

That depends on what you’d consider “good” email capability, or what price would be “comfortable” for you. It also depends on what countries you’re heading for. But, in general, any BlackBerry or Treo that works with the AT&T (formerly Cingular) or T-Mobile networks here in the U.S. will work in Europe and in many other regions. And both have what I consider good email capabilities for the price, which can vary, depending on model, and be as low as $99.

In general we love our new MacBook laptop, but there is one thing we’re not sure how to work around. We find that there are some Web sites that don’t seem to work well with the built-in Safari browser, and on some sites, we are unable to play a video. Is there a solution?

Yes. For the Web pages that don’t work well with Safari, you can download and use as an alternative the Firefox browser, which comes in a Mac version that is essentially identical to its Windows version. You can get Firefox, which is free, at mozilla.com.

The videos that won’t play were likely produced in the latest version of Microsoft’s Windows Media format. Microsoft offers free software that allows these videos to play on a Mac. It’s called Flip4Mac and can be downloaded at: www.microsoft.com/windows/windowsmedia/player/wmcomponents.mspx.

It depends. If you need a relatively low-capacity player that stores music in flash memory, like the iPod Nano and Shuffle, you might look at SanDisk’s Sansa line, or at the iRiver players. If you want a high-capacity player like the full-sized iPod, which stores music on a hard disk, you could consider the new Microsoft Zune, or the hard-disk players from Creative. But all of these players offer a less satisfactory experience than the iPod does with buying and/or synchronizing music.

Also, only iPods can directly play the songs you have purchased from iTunes. So, even if you can get these purchased song files onto your new player, they won’t work. To overcome this obstacle, you will have to go through a tedious process. You must first burn, or record, each purchased iTunes song to a CD. Then you’ll have to re-import, or “rip” the songs from the CD back to your hard disk, as MP3 files. Finally, you will have to manually re-enter all the information — song title, artist name, album, and so forth — for every song.

I know the new Cingular Treo 680 works on a much slower network than the Verizon and Sprint Treo 700 models. But is it slower or faster than the older Treo 650 from Cingular? Will Cingular get the 700?

Both the 650 and the 680 use the same network technology, called EDGE, which is much, much slower than the network technology that is used by the Treo 700 on Verizon and Sprint. Neither the 650 nor the 680 can take advantage of Cingular’s new, faster network technology, which is called HSDPA, nor can they be updated after sale to do so.

I can’t say for sure what other Treo models Cingular will choose to carry, but the current 700 versions are incompatible with Cingular. The only other new Treo that is compatible with Cingular is a model called the 750, now sold in Europe only, and due in the U.S. late in 2007. In its European configuration, the 750 runs on faster network technology than EDGE, but cannot handle Cingular’s fastest network.

I have an internal DVD burner that I removed from a desktop computer that failed. I want to convert the burner into an external drive. Is there any way of doing this?

You can find external enclosures for DVD drives that will allow you to connect such a drive to a computer via a cable. Just search online for “DVD burner enclosure” or some similar phrase. I can’t guarantee that your particular drive will work as an external unit in an enclosure or that you will have the skill necessary to convert it.

Here are a few questions about computers I’ve received recently from people like you, and my answers. I have edited and restated the questions a bit, for readability. This week my mailbox contained questions about Cingular data networks, the quality of Compaq laptops and options for connecting an iPod to home speakers.

In your review of the new T-Mobile BlackBerry Pearl, you said Cingular Wireless has a data network that is much faster than the EDGE network that T-Mobile uses. But I have a BlackBerry from Cingular and it, too, uses EDGE. So how is Cingular faster?

In 80 cities, Cingular has now rolled out a new network based on a technology called HSDPA that, in my tests, can be 10 times as fast as EDGE. However, most of its phones and digital devices haven’t been updated in new versions that can use the new, faster network. So far, only a few regular phones and laptop data cards from Cingular can use HSDPA. Its data-centric hand-helds, like BlackBerrys and Treos, are still stuck on EDGE, which Cingular continues to maintain alongside the new faster network.

But Cingular plans to offer new versions of the data devices in the coming months that can take advantage of the new, higher speeds. By contrast, T-Mobile has nothing faster than EDGE. Verizon Wireless and Sprint also have networks that are much faster than EDGE, based on a technology called EVDO. They are way ahead of Cingular in both the number of cities deployed and in the variety of devices that can use the highest speeds. For instance, the Verizon Treo I carry uses EVDO and can download Web pages and email attachments much more quickly than any EDGE device can.

There is a catch. With Verizon, Sprint and Cingular, even if your phone or data device can use the highest-speed networks the carriers offer, they will drop down to a lower-speed network if you enter an area where the higher-speed coverage isn’t available.

I bought a Compaq laptop in January 2005. Now in August it will not turn on. Naturally I only had a one-year warranty. The Geek Squad tells me I need a mother board, and that will cost more than a new laptop. Does Compaq have a history of only lasting a little over a year, or did I get a lemon?

Neither my email from readers nor anything I have read suggests that Compaq computers typically last only a year or so. However, reader surveys published by Consumer Reports and PC Magazine rank the Compaq brand (which is now owned by Hewlett-Packard) at or near the bottom in categories like how often its laptops need repairs and how reliable they are.

In general, I believe that as the factories in China (where nearly all laptops are made) jam more powerful and numerous components into slender laptops, quality and reliability are falling. Even Apple, which ranks at or near the top on the surveys I mentioned, is having problems with some of its newest laptops (and I am not referring here to the burning batteries Apple and Dell purchased from Sony).

Are there any good, effective options for getting an Apple iPod to work with a home speaker system? I guess I’m envisioning a “receiver” that allows an iPod to dock with it.

There are lots of products on the market that allow you to connect an iPod to a home audio system, or even just speakers. They range from simple audio cables you can buy at Radio Shack to iPod docks that connect to speakers or an audio receiver, and even wireless approaches. Apple itself makes a $19 cable and a $39 dock for this purpose and also sells a complete kit, with dock, cables and remote, for $99. But other companies sell similar products as well as self-contained docks.

There are way too many of these to list here, but there are some Web sites that can help you. Apple has a Web page listing some accessories, at www.apple.com/ipod/accessories.html. More are listed at Apple’s online store, at store.apple.com, under iPod Accessories — “Cables & Docks.” Another good source for information about this topic is ilounge.com.

Here are a few questions about computers I’ve received recently from people like you, and my answers. I have edited and restated the questions a bit, for readability. This week my mailbox contained questions about waiting for the new Mac OS, using an iPod with an old version of Windows and getting broadband in rural areas.

I am planning to replace my aging Dell desktop with one of Apple’s iMac machines. Now that Apple has announced that the new OS X Leopard will be released next spring, is it advisable to wait for Leopard’s release to buy a new iMac? Or will the current iMac be able to run Leopard when it is released?

If history is any guide, an iMac you purchase now, or in the next few months, should easily be able to handle Leopard, which is the sixth version of Apple’s Mac OS X to be released since 2001. Since Apple upgrades its operating system far more often than Microsoft does, the upgrades tend to require less of a jump in hardware capability. (Microsoft’s forthcoming new version of Windows called Vista, due in January 2007, is the first major overhaul of Windows since 2001.)

However, Apple hasn’t promised that every new feature of Leopard will run on any iMac sold now, and the company has coldly cut off users of older models in the past. So, if you can wait, do so. It’s always better to buy new machines with a new OS preinstalled, even though Apple’s OS upgrade process has generally been much quicker and more reliable than Microsoft’s. Another benefit: Apple typically charges existing users $129 for an upgraded OS, even if their machines are only, say, six months old. But new Macs next spring will include Leopard free of charge.

Even if you can’t wait until spring (you said your Dell was “aging”), consider waiting a few months to see if Apple brings out a new iMac with Intel’s latest processor, the Core 2 Duo, which is faster and more efficient than the Core Duo in current iMacs. I have no information that this will happen, but you should know by November or so.

I’ve got a new iPod I want to use with my Dell Dimension 4100 running Windows Me, but the iTunes software will apparently run only on XP or 2000. What’s my best bet for software to load files onto my iPod?

Try a product called XPlay 2, by Mediafour. It is specifically designed to work with older versions of Windows, including Windows Me. It costs $30 and can be downloaded at mediafour.com/products/xplay/. There is a free trial, but it is limited.

We live on a dirt road in rural Virginia with no cable and can’t get DSL. How can we get broadband? We would prefer not to do a satellite connection because you still need a phone modem to send material. Is there some kind of fast wireless connection we could get from our PC to our ISP? I see laptops with wireless antennas sticking out of them around here and they must transmit to somewhere.

Satellite Internet access has improved, and no longer requires a dial-up modem for the return path — in fact no use of the phone line is needed at all. Of course, as with any satellite service, your house must have a clear line of sight to the area of the sky where the particular satellite you use is situated. For more information, see www.hughesnet.com.

Another option, if you have good cellphone coverage, is a broadband cell-phone modem. It uses the cellphone network to connect you to the Internet at speeds roughly comparable with a slow home DSL line — which is still much, much faster than your current dial-up connection. This is probably what all those laptops with antennas are using.

These cellphone modems, using a technology called EVDO, are offered by Verizon and Sprint, and Cingular is slowly building a similar wireless broadband capability. For more information, see the Web sites of the phone carriers.

In some parts of the country, but not Virginia, a company called Clearwire is offering wireless broadband to rural homes.

Here are a few questions about computers I’ve received recently from people like you, and my answers. I have edited and restated the questions a bit, for readability. This week my mailbox contained questions about recording features for newer iPods, saving files to “write protected” floppy disks and choosing the right cellphone service for your business.

I would like to record my yoga classes on an iPod for playback later, but all of the recording accessories I find work only with older iPod models. Is there a recorder that works with the new video iPods?

Yes. Next month, Belkin will begin selling a $70 plug-in recorder for the video-capable iPods. It’s called the TuneTalk Stereo, and features twin mikes, plus a jack for hooking up an external mike. I haven’t reviewed it, so can’t say how well it works. Another option is to buy an MP3 player with a built-in recorder, like Creative Technology’s Zen Vision: M.

I tried to save a letter on a floppy but received the message that the file couldn’t be saved because the floppy was “write protected.” How do I get rid of this write protection?

Floppy disks have a plastic tab that can be moved up and down to either allow data to be written to the disk, or to block the writing of data, which means the disk is “write protected.” This is intended to keep important files from being overwritten. The tab either exposes or covers a hole in the disk.

The tab is set by default to cover the hole. This allows the writing, or saving, of files. I’m guessing you moved it accidentally, so the hole is exposed, which protects the disk. To correct your problem, turn the disk over to the back, and look for the tab in the upper left. Move it to the position that covers the hole. You should now be able to save your file.

Our growing small business in Pasadena, Calif., is struggling with our decision on the right system and device for cellular phone and email. We are trying to decide between Cingular and Verizon Wireless as carriers and the Treo and the traditional model of the BlackBerry, the one with the full keyboard. What is your recommendation?

On your choice of carrier, I always suggest people decide based on coverage and reception in their home area, their office area and the areas to which they travel. Price and phone selection are important, of course, but they make little difference if you can’t get calls or email where you need them. So ask around and try and determine which one has coverage and reception where you want it.

On the devices, I generally prefer the Treo, which has a much better calendar and address book, and other features the BlackBerry lacks, including a camera, strong multimedia capabilities, the ability to edit Microsoft Office documents and a vast trove of third-party software. However, when you set up the BlackBerry server to work with the BlackBerry devices, it is a powerful email tool and an adequate phone.

One thing to note: Verizon Wireless has much faster data service than Cingular in most cities. The Treo 700s sold by Verizon Wireless use this faster service, and are more advanced than the older Treo 650 model sold by Cingular. The BlackBerry 8700c sold by Cingular is the best full-keyboard BlackBerry model, but it’s much slower than the older BlackBerry 7250 sold by Verizon Wireless, because of Verizon Wireless’s faster network.
