That's cool, but why buy it in the US when it's out here? It's going to be a few ££ cheaper but you are stuck using a step down converter or you will have to buy a non-official charger at more expense.
I bought mine in Japan when it first came out, but if I was buying one now I'd get it here (although I have the lovely enamel blue one which isn't available in the UK, but you can get the black which you can't get elsewhere

)
