As stated, it includes BlueTrack, Microsoft's latest achievement in sensor technology that combines the precision of laser with the broad scrolling power of traditional optical mice to achieve smooth tracking on almost any surface, including carpet and other rough surfaces where a normal mouse would likely fail. The mouse that comes with the Wireless Comfort Desktop 5000 is basic, but functional. The keyboard is powered by two AA batteries included in the package, and there's even a small LCD that glows red when you need to swap them out with new ones. Like the Logitech Wireless Keyboard 5000, all of the media control shortcuts live on top of the keyboard to allow for one-touch access to your preferred applications and tasks. The top row of buttons has everything you need to take it with you on the couch and control a living-room PC. The perforated rest pad that sits just below your wrists gently cushions your hands as you type, leaving little pressure on the rest of your arms. Microsoft wasn't joking about comfort, either.
The short depression distance and the soft (not mushy) touch of the keys both lend themselves to a rather quiet typing experience. It's not a huge deal, and definitely doesn't require as much time to get used to as the ergonomic split-keyboards we were typing our average speed in less than two hours into using it. The middle rows are affected the most by this bend-the G and H as well as the B and N buttons are significantly wider than the rest, resulting in some mistaken key presses during the initial learning phase. The big difference between the two, however, is the keys on the Microsoft 5000 keyboard aren't evenly spaced or uniformly sized-since they're forced to conform to the Comfort Curve. The layout of the keyboard bundled into the Wireless Comfort Desktop 5000 is similar to the recently reviewed Logitech Wireless Keyboard K350 that splits the keyboard in half and turns both sides up so your wrists are angled in a less stressful position.
