But the demo units over at Barnes & Noble, are more messed up then I thought, I was on a second demo unit at the closest store (which is shutting down

), I found out that- mostly due to the current firmware- an overly busy 3G population in the store could render the nook unusable.
First off, both of the screens hanged blank, I had to wait three minutes for it to respond.
Standby became more of a pain to exit because of wireless interference.
And finally, the screens started blinking back and forth furiously every other second, I returned to the demo unit a while after to find it still blinking like crazy, and the lady at the stand was blowing steam trying to un-hang it.
