Raspberry Pi is a lot of fun to own and learn about. You can pull all kinds of neat thing with these mini computers. Take the Frankentabletbook project for instance: it’s all about connecting a Raspberry Pi to a Kindle to make a productivity tablet based on the Franklin Day Planner. You will need to install remote desktop service on the Pi, connect your Kindle via remote desktop over WiFi and configure the Pi to act as a WiFi router. Once you install Git, Node.js, and DocPad, you are ready to go. You can find the instructions on ammonsonline.com. A pretty fun DIY tablet project if you ask me.
