Ah, yes... if you insist on buying yet another keyboard, mouse, USB hub, 
micro-USB power adaptor, WiFi dongle and HDMI cable with that...

If you already do have those components flying around your house 
somewhere, you /might/ however try ordering a bare Pi mainboard for 18 
to 40 GBP, depending on the model. At Maplin. No further hunting required.

Is Haskell a high-level enough language for your taste? :P

Not to mention C, C++, C#, Ruby, Perl, Python, Scratch, Java, Pascal and 
BASIC of course; you can even control them from the command shell:

Well, yeah, that's the usual way to drive anything even remotely 
power-hungry with any digital controller.

As for the 0.3mW, if you go for the Model A you can go up to 0.5mW.
