I ordered a 16GB Nexus 7 yesterday from my local EB Games (Australia). The release date here is 27th July. It's a little more expensive here. The RRP is $319, but EB Games is selling them for $298 (inc tax) and I don't have to pay shipping.

I'm currently living in an iOS world with an iPhone 4S and iPad (3). I hope no one holds this against me.   This will be my first Android device. I would sometimes jailbreak my iOS devices to open them up, but I am looking forward to having a device that is more open to begin with. Although, I expect to root it for USB-Flash drive access.
