What was the increase? something like 1150 to 1600 mAH? So that's 1.39 times battery life... So, if the normal business user gets, let's say 4 hours, out of their G1, this will give them 4*1.4 or roughly 5 and a half hours. I'm sorry, for that little improvement, I'd be embarrassed to admit I spent $50. So I can't blame them for not speaking up. But again, that's just me. I think I'll add that to my sig now...
