Thanks BT for the review.

I think we'll see nice things using the GPIO pins, just have to make the duino and the pi communicate.

Well, I say 'any old charger,' but I found that it didn't like the charger for my HP TouchPad - which is odd, 'cos it's a 5V 2A model. Swapped it out for a 5V 1A I had lying around and all was well. Still haven't figured that one out...

However from what I've read on the official forums, few of the alpha/beta boards are actually using more than 500mA under normal usage. Probably a smart idea to have an adapter that can supply at least 700mA, especially if you're loading the USB bus, but it'll be interesting to see what the power usage in a real-world scenario actually is - especially if it's running headless with no KB/mouse connected.

It's sad really because it is a lovely crisp screen but its limited to dvd's or an analogue video signal (RCA or 3.5mm jack). Back when I had a nokia n95 I used to be able to hook that into it so I had my phone screen displayed on it, but phone companies don't seem to do that anymore :(
Anyway I'll keep an eye on the development of the PI and keep my fingers crossed that one day I can put one in my car.

Hooking it up to my Maplin-branded pile-of-crap Kill-a-watt equivalent gives me a reading of 3W, but the fact that the figure doesn't change under load suggests that I'm hitting the lower levels of its capabilities. By contrast, the SheevaPlug mentioned in the article hits about 5W under load on the same device.

Either way, I'll find a few uses for it.

I am not sure if it will produce a nation of programmers as intended but I would really love to get my hands on one.

It is a very cheap piece of hardware which schools <edit> and children </edit> could easily afford, but this isn't going to turn every school child in 5 years time into a programmer.
It will be interesting to see what's in store for the upcoming educational launch. However, as a nerd/hacker, I cannot frikkin' wait to get my hands on one. Or several. I really wish RS would tell me when I can expect to be able to order one!
PS, by the way Rory, HTML is emphatically not programming - the clue is in the acronym: HyperText Markup Language. It's an easy start, but it's not programming.
