I think the thing is, people want keyboards. tablets are not easy to type on and keyboards for tablets leave a lot to be desire. most are thick and finicky. in addition unless they have a wacom driver, they are not easy to write on. that is the biggie thing I miss with the note 10.1 tablets. though you can write on the zenpad, the note was better and more precise.
maybe this thread should have had a poll to find out what they mostly use their tablets for, whether for gathering dust, playing games, reading or whatever.
