Check out this remote with a built in trackball that lets you use it as a wireless keyboard with your media center PC.
The EZ Commander might look like an ordinary TV remote, but look closely and you’ll find a tiny trackball in the center. Rather than control your stereo system the EZ Commander Trackball Remote acts as a wireless keyboard and mouse replacement for your PC.
Perfect for use with a media center PC or running a presentation from your laptop. The included IR receiver plugs in to a USB port and gives you full control up to 30 feet away. Use the keys to execute common PC functions or control your audio and video files with the “media center” mode which supports Windows Media Center.
The trackball works just like a mouse. Push down on the ball to left click, or use the buttons above the trackball for right or left clicks. You can even type simple text using a T9 input method similar to texting on your cellphone. The included laser pointer lets you gesture at those all important PowerPoint slides.
The EZ Commander Trackball Remote is available to buy online for $59.99 from ThinkGeek.
