Just echoing some common sentiments here:
Upgrade: I upgraded with no problems. The battery was at 3/4 charge and when finished the battery showed full charge.
I use a 2-gig SD card. Access to titles does not faster to me.
Vulunerability: no one's tried to steal my Reader.
Whine: I don't understand why Sony can't put one of those car-alarm systems onto the Reader; you know, the alarm that
SCREAMS at anyone who gets too close or who tries to access my Reader without my authorization.
