I had a first gen iPad, and it's battery was spectacular, and I'm not complaining about the iPad 2's battery, because it's great as well, but it isn't quite as good as what the first gen's battery was. When I brought my first gen iPad to school (~6 hours), I would come home with about 60% battery left, but with the iPad 2, I come home with around 50-40%. I still have a battery that lasts me twice what I need, but it's a bit misleading if you ask me if they advertise the battery life as being the same.
