lgreenberg - no need to explain, looks like you got a good one! I don't view this key movement as a big deal. I type like crazy on it still, not sure that the slight movement hinders my typing in any way.
The dust is annoying though. I had just taken off the original screen cover (the crappy plastic one that comes with the unit) and was about to apply a new invisible shield when i noticed that dust below the screen. But it was too late, I had already wet the invisible shield! Oh well, I'm just praying that the dust accumulation doesn't continue.
