I also played with one at an AT&T kiosk at the mall the other day.
It's glorious. I was skeptical of the original Note when it came out because of its size.. and still was of this when it was announced. But after seeing it in person, it definitely still fits in your hand nicely. My only concern is that it's very slick. I'm definitely going to need a case with a rubberized texture on the back or something. But other than that, this is absolutely amazing.
I know the display has been outdone now with the DNA announcement, but for my money, I'll take a larger, but not quite as good display, if it has a big removeable battery, and expandable storage.
I can't wait for the 29th!
