lol I've just got itchy fingers.
Friend gave me a 128gb ipad air that was dead (would not charge) to dismember. Turns out there is nothing wrong with it - well apart from being an ipad air (both speakers are together at one end - it actually has stereo mono sound).
So I'm looking at isense - can pick one up for around £70 plus whatever the customs would sting me for.

But reviews don't look great for small stuff and I don't want to print people - well until I can afford a full colour printer anyway, at which point there would probably be money in it.

Ah well I'll just have to keep my hands firmly in my pocket till the technology improves and gets cheaper.
