I'm happy with my Vivo RT and it does what I expected it to do, but tablets are a niche product from what I'm seeing so far. We'll see what happens in the next year, but touch is kind of a pain in the a$$ for some tasks. At this point, it's a dedicated surfing, OneNote, remote-Desktop, sudoku machine.
But that was what I wanted. Everyone I know who purchased an iPad as some kind of productivity machine stopped bringing it in to work because the form fact doesn't lend itself well to that kind of work.
