i think there are already a few threads ongoing with this discussion. see what other people have been saying there.
I just physically held a 10.1 sammy and it was very nice feeling, felt better in my hands than the TF.
with that said, I am totally biased against samsung (from experience), and can't bring myself to buy anything more from them.
the hardware is literally 95% the same. I am interested in the dual wireless radios, meaning you could tap into a 5ghz wireless N setup, but not sure if that is confirmed hardware or not.
after the dust has settled, I am confident the TF was the way to go. they have proven they can deliver timely updates.
