So far, I love it. Display and performance is outstanding, and the S Pen is surprisingly useful. Writing out text instead of typing it is a bit long winded but quite satisfying, though the novelty may wear off after a while. The keyboard is excellent, no not as good as a full sized keyboard but combined with the advantage of the size and convenience of how easy it is to just snap into place it's a great compromise. I was going to buy a smaller case fo just taking the tablet out and about but bought a neoprene sleeve instead. The case feels liks it leaves the edges vulnerable. The glass back does look fantastic but feels so fragile.
Haven't noticed any hissing from the speakers but I'll turn them up and give it a proper check later.
