Well it only came out a month or two ago, launching 3.0 (can't remember the name sorry) and everybody all over the world wanted to update as soon as possible to 4.0 (ics) so Asus sent out the promt so we updated but it seems like there's still a few bugs :/
But other than that, I recommend the Asus transformer prime to anybody
Heck, maybe android will take over and become a desktop os in the future
Cheers
