Got this deal from "longstack" at http://forums.whirlpool.net.au/forum-replies.cfm?at=1738731&… - not sure if there's an expiry date to it.
Basically, as per title description - not such what else I need to say about it. I went to the local Myer just then and bought it via price matching from the Bing Lee website (as a bonus, I managed to get a black one via price matching). Seems to me to be a good price for Australian stock with Australian warranty from a large store.
Edit: as per poster below, use "PAYPAL10" when paying by Paypal for additional 10% off, bringing price down to about $430 (wish I saw that before I bought it!)
First released (internationally) in March 2011 - so nearly a year old. The next generation of tablets are on their way from these guys with a much better processor, so to be honest $478 doesn't seem like a great deal to me.
