I have an HTPC (Home Theater PC) hooked up to my TV and I've always used a wireless RF keyboard that's done a decent job but often has trouble without a clear line of sight even from less than 10 feet away and the 6 AA batteries always die very quickly.

I finally opted for a new mini bluetooth keyboard, hoping that the longer range of bluetooth and the rechargeable lithium ion battery would solve my problems. As neat as the light, tiny handheld keyboard + trackpad is, it's a pain because it often loses its connection and the trackpad movements are always delayed and imprecise.

It just hit me 10 minutes ago that I have another handheld bluetooth device: my Droid phone. I did a quick search in the Android market and found a phenomenal open source app called pRemoteDroid. You just install the app on your phone, download and run the server software for your PC, then connect your phone to the desktop app via bluetooth or wifi and that's it!

Not only is it free, open source, and simple to set up, but the connection is really solid, mouse movements are precise and instantaneous as are keyboard strokes, you can capture screenshots (used as the background in the Droid app), and you can quickly, easily navigate folders and launch files via your phone.

I'm really impressed with this software and encourage anyone looking for a PC remote control solution to consider using it.
