I've got an iPad 3 which I'd consider selling (or trading for a MacBook?)
Still has 8 of the original 12 months warranty remaining, although the iPad itself is only about 6 weeks old (it was a replacement from Apple when I cracked the screen on the original one).
It's the 32gb WiFi and 3G version, RRP £579 on the Apple website at the moment. I have the receipts and the original box with all the original accessories, and I'd throw in an Apple AV Composite Cable too, which has never been used.
I haven't really given the price much though, but drop me a PM if you're interested and we can take it from there.
