I like it. Tablets are already big (unlike my Kindle that I keep in a case) so I'd rather use them without a case.
I don't care that much about scratching the back. I figure if I'm careful with it and put it in a neoprene sleeve (with smartcover over the screen) when I'm putting it in my briefcase etc. it should be fine.
Though I did have the same worry about the cloth side of the case that touches the screen picking up things. But I haven't had much issue with that with my Kindle case and I often have it folded over and sit it down with the clothe side that touches the screen on a table etc.
