Just came back from Currys and handled the Tab in a limited way(with the wire tethering etc.,). I did not feel it as being very heavy. Much lighter than the ipad. Good responsive UI.
Little confusing, typical of all android, since i am over-drugged(but i love my maemo better) by IOS.
It seems little too big(or maybe narrow/rectangular) to read fiction etc. and more than a little too small to read technical pdfs. The ipad feels more squarer.
More number of lines per page in an epub to read, with too few words in each line. I will be mentally putting more Carriage Returns per page.
People have told its funny to see me talk with a Dell Streak. And that will be doubly so for the Tab I guess. It has a high sillyness quotient, unless used with a headset/bluetooth.
What these devices need are good grips. I havent found much comfort in the covers.
I have a Marware cover for my ipad that has a simple strap in the back to help in gripping. This works while standing. However i am not very comfortable using this while i am in bed. thats when the ipad feels real heavy.
Maybe the heavy part of the Tab can be solved by a better cover, one that helps the grip in different positions.
Something like this might, i think, have a comfortable grip:
