I'm away on holiday at the moment in Canada and have been toying with the idea of buying an iPad whilst here. There is a small saving on the UK price for the 16GB - $519 -> £326 (exc taxes) I assume it comes with a 2pin power plug - can this be changed easily? If I had a fault with it would Apple UK be OK if I sent it back to them ? Anything else I should be aware of ? Thanks.
