FWIW, I must have been one of the last people to get my 800 from Circuit City. Ordered on the 25th and recieved on the 27th.
I resisted the temptation to play with it before it had finished charging. Took almost 3 hours. I used the time to poke around here and read the manual.
Haven't had a hint of a problem so far <frantically knocking wood>
Added a couple mem cards and have installed FM radio. Probably will get to know it as-is before flashing to 08. Check more feedback on it here.
I'm not in a big hurry.
