I went back into the Apple Store today and joined the que, which was shorter than yesterday.
After an hour and twenty minutes I left with a white 16gb.
The wait wasn't as bad as I thought it would be, as there were chairs to sit on, albeit a slightly surreal experience.
Very pleased with it.... only downside I've found so far is that there is a stuck pixel on it, which is so small its barely noticeable, and doesn't show up when watching videos, so no biggy. But if you buy one in store, I'd take a good look at it... which I didnt do!
