Chalk this up in the nifty column! RemoteDroid, an app in the Android Market, allows the T-Mobile G1 to become a wireless mouse & keyboard combination for your computer. The way it works is that it communicates through WiFi--check out the video to see some pretty cool implementation.

You can use the touchscreen and trackball to scroll around, the keyboard is fully functional--it's really great to see developers have their turn at the T-Mobile G1 and create unique apps for it. Check out the video to see how this app works!
