I've been using the extended battery for the past couple of days, and it is definitely more practical than the standard battery. I have come to accept the fact that if you carry a Windows Mobile device, you either need to carry a backup battery and/or go with an extended battery. It just sucks that you have to drop $50 bucks for it! I wish VZW would give the option to purchase the PN-820 with the extended battery versus the standard battery that came with the phone...

...or maybe even include it, like they did with the i730! =)
