I was worried about the USB port at first, but mine still seems extremely sturdy. So maybe it was a defect not caught by quality control for some N900 units.

The stand itself is entirely useless (especially compared to the n800's).

I had problems with getting the N900 to respond to a wall outlet charger when I first got it, but after a reflash it seems that problem has gone away.

My slider is a little loose however (I should probably tighten the screws in the back). Not as resistent as when I first got it.
