Just got mine a few hours ago. Only thing I've noticed (besides the slightly loose battery door) is that my escape (or back) key feels like it has a middle stop, like on a camera shutter where you can feel resistance halfway, then press harder for a full click. The half click works, so if I just press normally, it feels fine, but if I press a little harder, I can feel two distinct clicks.
Ok, this is really starting to annoy the crap out of me. It's like if I'm not paying attention, I hit the escape key too hard and it almost feels like it's interfering with the bottom of the screen.
