You can use a desktop on wireless. Is your husband looking to
move a desktop from his personal PC to your laptop? Are you looking to move from one computer to another? If it is the same computer and he is logging into his own account, it won’t matter if he has wireless or not.

Yes, the desktop can be used wirelessly. Buy a USB wireless adapter (if there is no WiFI adapter in the machine) and connect to the hotel’s WiFi network. Another idea (and less cumbersome).is to back the eBay stuff up onto a portable hard drive to use on the laptop. Might be useful to to back it up anyway in case the desktop dies young unexpectedly.
Yes, a desktop can be wireless. What is needed is a wireless adapter.
There are three basic types. an integrated adapter, an adapter card and a USB adapter. The integrated adapter id built into the
motherboard. The adapter card fits in a PCI slot on the motherboard, an easy thing to do, The USB adapter plugs into a USB port. Each has advantages. The card approach and the integrated are always in the desktop and if moving the system, its hard to lose it. The USB adapter ties up a USB port on the system. This is no problem if you have two or more ports but if you have a USB printer, keyboard, mouse, camera, etc you’ll need a USB hub. The USB adapter can also be used on your laptop if it doesn’t have an integrated adapter. All of my desktops have wireless adapters in them.

answer:
The MacBook Pro is about $2000-$3000. I comes with everything you want. I would imagine the range of upgrades might be less than with a Windows based machine but I don’t know for sure. A MacBook is less money and some that comparably equipped.

If you are willing to look at Windows based machines you can get a lot for your money. I would recommend PCWorld, PC Magazine, and Computer Shopper as places to look for their recommendations. They are very current and can give you reliable information.

answer:
You can add resolution but it will not improve the quality. If you start with a video of poor quality, the final product will be of poor quality.

The problem is that you can’t add any more data than what was there in the original image. Its like resizing a picture larger – all you really get for your trouble is a larger, blurrier image.

If you need a wireless card that slides into the PCMCIA slot of your laptop, avoid the Raytheon model 2402o ones for sale on Ebay like item 310018548922. They linstall in Windows XP just fine, but they show up as an ethernet card with the message that a cable is unplugged, not as a wireless card looking for an access point to accociate with. I finally got some information out of Raylink, and they will ONLY work with a Raylink Access Point! What a deal, put one of these in your laptop and drive around for a couple of days and MAYBE you will find a coffee shop to get on line in.

If polyphonic ringtones are important to you, opt for models that offer nothing less than 16 polyphonic tones for reasonable sound qualiiy. This means it has the sounds of 16 instruments, which can be played together in the ringtone.

Look for a phone with a Microbrowser feature. This lets you surf the wireless Web. If your phone features a WAP (Wireless Access Protocol) browser, you can use it to view websites that allow this mobile-viewing feature. Also, some Internet-ready phones can be used as a fax modem, but you’ll need to purchase the proper data cables to benefit from it.

Always on the go? Look for a phone that has Bluetooth or infrared. Both features allow you to wirelessly connect with external devices. A phone with an infrared port allows info to be exchanged wirelessly with PDAs or PCs.

Besides talk time, the length of standby time is just as important, especially for those who do not carry chargers. A three to seven-hour talk time is not unusual. But find out whether the battery has enough standby time to last at least the whole day.

Handheld or palm?: Decide on whether you want a keyboard or a stylus. Palms are stylus or pen operated, whilst a handheld is larger and has a mini keyboard to it.

Screen: For image quality, check the screen resolution, which is measured by pixels per inch. The more pixels there are, the higher the resolution, the sharper the images. Generally, a palm with a 4-inch screen supports a resolution of 320 x 320. For handhelds, a typical screen size of 6.5 inches supports 640 x 240 pixels.

Memory: This depends on your needs. If you need more than what’s usually offered, opt for expandable PDAs that feature built-in expansion slots that allow additional plug-ins for an external memory card and USB ports.

Handling: With handhelds, the keypads are tiny and may be annoying if you have large hands. Lefties should also note that PDAs are designed for the right-handed.

Operating system (OS): There are three major operating systems available depending on the brand you get: Palm OS, Windows Mobile by Microsoft and Symbian OS. Windows Mobile is pretty popular mainly because it’s just like using Microsoft Windows.

Connectivity. To get online, you need a PDA with built-in WiFi or Bluetooth. Some PDAs come with a PC Card or Compact Flash slot, where you can connect to the Internet using external cards.

Don’t let the battery die completely. However little you use your iPod, charge it fully at least once every three weeks to prevent the battery from going flat.

Keep cool. Very cold or hot temperatures cause faster wear and tear on the battery. So do not leave your iPod in the car underthe sun and use covers that allow heat to dissipate.

Hold & Pause. Set the iPod’s hold switch when not in use. Alternatively, pause or turn it off by pressing the play button for two seconds.

Turn off the EQ. The equaliser (EQ) forces your iPod’s processor to “think” while it changes frequencies of the music which can sap the battery.

Set the timer. While extremely useful when searching for songs, the backlight is a big battery drainer. Using a short timer or turning the backlight off will use less power.

Use small files. The iPod has caching techniques to play songs while using the least amount of power. Battery life is best with compressed files (usually MP3 orAAC) rather than full-quality AIFF or WAV files.

Know your network. Check which network most of your friends and peers are on and consider switching to it. Changing networks is easy and you can often keep your number for no extra charge.

Get an IDD card. Great for long-distance calls. Not only does it offer better rates, it also ensures yourtalktime is limited. Most networks have a two-way charge for overseas calls. Or, stick to SMS.

Check your bill. To ensure you catch errors and identify hidden charges. If you find a mistake, dispute it; you’ll often receive credit on future bills.
