When building an HTPC system, one of the main problems is finding a decent keyboard and mouse that won't take up too much room. Often a good keyboard is just a standard full sized desktop keyboard in a wireless version. Then there is the issue of cursor control. A mouse often gets misplaced, and remote control units are awkward at best. VidaBox's new Premium Wireless Keyboard features a built-in optical trackball, and the size is as compact as a laptop keyboard.VidaBox Premium Wireless Keyboard Review
