Battery life can be kind of short with the thin battery, but I keep it plugged in to my computer all day so that it can stay synced and charged. The only thing I'd wish for is a better camera for times when I don't have a dedicated camera in my bag.
+1 on the Blackjack. An additional advantage for me is that I can tether it to my laptop and have an HSDPA connection in most places in the US.
