Best Buy pre-orders, Evo battery life...

Hi all. First post, but been lurking for a few weeks. The local BB (North Shore New Orleans) pre-orders are at 60 as of Fri. morinig. Wife and I are 9 and 10. They said today is the last day to ensure an evo on the 4th. Last week they weren't going to do appointments, when they had 15 pre-orders, but I think they will have to. There are 5 other BB's in the region, all larger than this one. So it seems word is getting out w/o a lot of advertising by Sprint. On the battery issue; when I got my Instinct there was a lot of complaining about battery life. In the case of the Instinct, battery life improved noticeably after several discharge-charge cycles. I suspect it will be the same with the Evo.
