I just wish they'd release the thing! I use mine for lecture power points and mark-up note taking. It barely lasts a three hour class, and if it's not fresh off the charger, it won't make it. It's an SP1, so I think the battery life is slightly improved on the 2, but I'm skipping this generation and getting the next. Meanwhile, the power cover should give me enough power to get through class and a study session or two on a charge.
Come on already, MS!!
