And other than having to be a little choosy about some of the hardware you plug into it, its awesome. I had a bit of trouble finding an SD card, wireless keyboard and webcam until I realised the PS3's eyethingy was an ancient V4L with no image compression and that works fine, it cost me 3 quid in a game shop secondhand.
I'm building a 'terminator' using a Pi and an Arduino back-to-back, the webcam on top, a mobile battery and 10 RC servos - 2-axis ankles, 1-axis knee and hip and a final pair to move the webcam (it doesnt have arms, yet anyway...) along with a laser pointer as a targeting reticule.
I'd already got the vision and targeting working on my big PC, that can tag my hands with a laser dot at 8 frames a second so I was surprised to see the Pi do it at the same speed. I've spent more than a few years learning embedded C+ trying to do what I'm doing, and the Pi makes it as simple as simulating it in a big PC, except its for real.
I've been using the guts of ARM-powered smartphones for my robotics up til now, as theres a plentiful supply of cheap processors laying around for free if you dont mind hacking them out. It doesnt take much to rip out a screen and keyboard and install Python in an old Nokia, but the Pi is a whole other order above those little beasts.
Looking at the photos, it seems not many really 'get' the Pi. Building a 'supercomputer' out of them defeats their object, as does running Windows - even though it IS a cheaper way of doing it. I guess they didnt grow up with Basic like I did though, and thats a big part of the concept. Teh Internets reacted like I thought too; type Raspberry into Goog and the most common hit is... A case for your Pi, designed by some wannabe who hasnt got one yet and thinks he can make money off it.
The BYO tablet is hysterical in its pointlessness, but clever all the same, and certainly beats the rest of the internet. The team building the boat, however, now thats an interesting project that really does push the Pi's design envelope. I like that one...
