Meet the MICILE: an exciting platform for tablet computing that lets you program in Python to develop all kinds of fun solutions. The MICILE Sidewinder Tablet has a Linux-based OS, front and rear facing cameras, WiFi, and a 7 inch display (800 x 480). What’s neat is this device is pretty cheap and optimized for development.
The developers have come up with a set of libraries that let you interact with the hardware of the tablet. The above videos should give you a better idea what MICILE is capable of. You can get your tablet for $99 + s/h.
