I like my Logitech keyboard, but I have wished more than one time that there were a wireless version of the Illuminated Keyboard when I am fighting with the wire to get the keyboard just where I want it. There are some uses, like for a HTPC, where wires simply won't work. If you are looking for a nice wireless keyboard that is perfect for use from the couch, the Adesso WKB-4200UB may be perfect.
The keyboard uses 2.4GHz wireless tech with 12 channels that it can change automatically to prevent interference. Wireless range is 30 feet and the keyboard has a small USB receiver. The best feature of the keyboard for the HTPC user is that it has a two-button track pad on the right side rather than a number pad.
That means you can type and control the mouse from one device. Power comes from a pair of AAA batteries and the keyboard has a switch to turn it off when not in use. The WKB-4200UB is available now for $119.99.
