I just got my Nexus 7 today and have been playing with it throughout work. So far, it's been a nice, solid device. 2 things: speed and size. I love this smaller format.
I do notice that the physics of Android aren't up to iOS level, yet. Scrolling/rubber banding all feel slightly awkward, with the exception of the home screen "holo-tilt".
What have you guys noticed? Also, know anyone else who has played with them? Let me know so I can invite them to the conversation!
