Mine is also very slightly off, although so little that it doesn't bother me. And I love the stand, since I read a lot while eating, and it helps to align the reader better for my viewing.
I haven't noticed the buttons pressed by themeselves, but that is due to the fact that I always turn the device off when not reading...
If the buttons are pressed by themselves when carrying, I'd also say that it is a problem.
I'm sorry if my enthusiasm has guided you to make a bad purchase.
