I'm going to have to revise my stance. It seems that the upgrade is causing my battery to drain faster than it did under OS2007. I did a full recharge (10 days/7hrs), put it in soft power off, and let it set for a day (no usage at all). When I came back, it was at 6 days / 4 hours.

Right now, thumbs down because battery life is a major factor in my book.
