I'm definitely loving mine. Sure there's some back light bleeding but only some portions at the edges and I don't even see them unless I stare intently. Compared to my aged Xoom, the high resolution screen is definitely "bleeding edge" technology.
As for the throttling, it does seem to be an issue according to some users. I've yet to experience any but then again I've yet to really play some heavy games on it. I'm on a custom rom with a custom kernel so maybe that helps. My experience so far is smooth and fast... well as fast as Android 4.2 can go now and definitely faster than my Xoom.
The Nexus 10 has a pretty fast storage with really good I/O performance, something Asus tablets seem to lack in.
