I've got some on order...
I'm not sure I 'get' the idea that it's an handy tool to learn to program. Whilst I haven't looked at the API, a linux based machine with openGL doesn't sound to me like a beginners computer...
If people wanted to program a device like that they'd all be writing software for their smart phones...
Still, at just over £20 a pop it's got a lot of potential and I cant wait to get me grubby hands on it.
As I understand it, it's not so much the machine itself that is a beginner's computer; it's the packages that will be on it, and the packaging of the OS that will make it an ideal training tool. i.e. it'll come pre-loaded with a programming environment designed to be easy to get into. The stated aim of the project is to give schools the equivalent of the old BBC Micro - something that's a doddle to program. Unlike the Beeb, it'll also be cheap enough to replace the inevitable killed ones; and cheap enough that schools can buy them by the dozen. I THINK, although I'm not sure, that the Raspberry Pi Foundation (the charity that designed & is making them) plans to give them to schools, as funding allows.
The price point makes it supremely attractive to anyone who wants a tiny solid-state computer. The company I work for will find them particularly attractive - we currently pay over £150 for a similar gadget, which is physically bigger & slower than the RasPi AND only has VGA on it (no HDMI). The biggest hassle we will have is re-compiling our s/w to run on the ARM chip (which is actually a bigger job than it sounds - fortunately I have access to a guru who can do that kind of thing).
I quite fancy the idea of using one or two in a car project I have planned.
