How's your Russian? Ours isn't, period. But Google helps a bit, so it might be useful to tip there's a Russian site that as of today has a lot of samples comparing the picture and video quality of the Nokia 808 with that of the Samsung Galaxy S III (!), the iPhone 4S and the Samsung Galaxy Note.
Frankly, we would have liked to see the Sony Xperia S and Nokia's N8 in this comparison as well, but it's a great thing they're already showing some results of both the new Samsung Galaxy S III and of course the 808 PureView this site is all about.
