I was really looking forward to getting the 10.1, but the addition of TouchWiz onto the stock Android makes me very hesitant. I'm hoping it will feature the same unlockable bootloader found on the Nexus One, Nexus S, and Xoom; if so, then I can just reflash it with a stock image if I don't like TouchWiz. I refuse to be at the mercy of Samsung to get updates for my $500 devices...
