Such a cool bit of kit
I have made it do video motion capture & voice recognition with a ps3 camera, added a Web server... loads of great stuff to play with. The NOOBS installer makes getting a working Linux platform trivial. Hook up to a wifi dongle and plug into a hdmi TV or monitor with speakers and get stuck in. Lots of great kits with everything you need for around £35.
Maybe time to look at some hardware bolt ons. Suggestions...
