I got one from the US and it flew pass my S3 in term of speed.
Project butter is really smooth. I've configured it and then send it back to the US for my sister over there as her gift :)
Bought a second one from the US but shipping to my sister address, my mum will be bringing it back to NZ for me.
Anyone interested in getting from the US with NZ credit card or PayPal?
$250USD for the 16GB version from www.adorama.com
Last week or so JB had a late night sale and the Nexus 7s were sold for $397NZ. Very tempting price even I have already had 2 lol.
