I've had one for about a month (upgrade from a Galaxy S).
It's a bit of cross between a larger Galaxy S and a smaller Galaxy 7" tablet.
I got it mainly because the larger screen helps with my eyesight problems.
So far I am happy with it, though I'd prefer to see it with the latest o/s version. It comes with Gingerbread, but I assume an upgrade will be available soon.
Sorry I can't offer much in the way of a practical review, but it's early days, and as I said, I'm happy with it. It still fits in the average shirt pocket!
If there's anything specific post again and I'll try to answer.
