Usually I’m not in the city on boxing day, so I don’t have much experience with finding post-Xmas deals. I did venture out this year however, and managed to snag a fairly good deal on a new mouse and keyboard at Best Buy. Listed at $199.99 CDN, I picked up the Logitech Cordless Desktop MX 5500 Revolution for just $99.
I had been using a plain old Dell USB mouse and keyboard since my last cordless Logitech mouse died about a year ago. It used two rechargeable AA batteries, but would consistently kill them with just a couple hours of use. The Dell mouse worked fine, but it’s most advanced feature was a scroll wheel. The Dell keyboard also worked well, and had some handy media controls on top, including a volume dial. Other than that however, I found it incredibly loud and the keys sometimes stuck. I knew it was time for a new mouse and keyboard, but it wasn’t a high enough priority for me to go searching.
I’m really glad I found the deal and picked up my new mouse and keyboard. The MX Revolution mouse has both a tilt scroll wheel and a thumb wheel (for more precise scrolling), back and forward buttons, and a search button. Best of all, it comes with built-in batteries and a charging stand so that I never have to change batteries. The keyboard includes the standard layout, plus media controls on the left and an integrated LCD screen on the top that can display the date and time, temperature, media information, and more. Both devices use Bluetooth.
The mouse feels very comfortable, and the soft built-in palm rest on the keyboard is a nice touch. The keys are incredibly quiet compared to my old keyboard, and feel very smooth. So far the battery life on the mouse has been great (haven’t had to charge it yet). The scroll wheel took a bit of getting used to (it turns into a hyper scroll wheel when you have a long document) but now I really like it!
I’ll admit that the LCD screen isn’t incredibly useful, but it is pretty darn cool. Based on the first week of use, I think I’m definitely going to like this mouse and keyboard.

I’ve had this mouse and keyboard for about a year now. Looks and works beautifully. Best of all, the battery life has far exceeded my expectations. The keyboard hasn’t needed new batteries yet, and the mouse I only charge maybe every month or two.
The keyboard does not work with Windows 7 on a x64 system using the latest drivers for Vista x64. Logitech does not support Windows 7. When using the keyboard, the top window loses focus regularly every 30 seconds, which makes it impossible to type.
