When is your Android phone more than a phone? When you turn it into a combination keyboard and mouse to control your computer. After installing a free Gmote server app for Windows, Mac, or Linux, Gmote creates an ad-hoc Wi-Fi connection with your computer--unfortunately, if you don't use Wi-Fi, you're stuck. The on-screen controls can stream music from your computer, launch movies from afar, navigate the Web, and control a presentation. It's not as powerful or sophisticated as some apps we've seen for iPhone, but it does the trick, and without charging a dime. Unless you opt for the $2.99 donation version. App developers like to eat, too.
