Except none of the development of the prototype has been done in the open. This just smells of the RISC OS post-Acorn A4 laptop fiasco: lots of prototypes but never anything in production.

I'll believe it'll be open when it is open. If - and I think it's a big if - they deliver on their promises it'll be a very interesting device.

I'd put a fiver on them missing battery life; software usability; thinness; and, most importantly, price.
