haha - I got it from kandco.com catalogue, £499 - getting the dock for xmas which they say gives another 8 hours battery, so will get 16 hours altogether fingers crossed
I can get about 7-8 constant heavy use from it atm, they said 9.5hours playing a film on loop with wifi off, but havent done that test yet
On another note I almost fried it just now with my DIY USB lead, I think rather than joining the same coloured wires to each other, for female to female, I was meant to reverse them.
Burning smell from the DIY lead, transformer seems unscathed
Pheff
