The battery will hardly run for 30 mins.
SB is not as battery draining as the previous generation.
In fact, I think the battery life comparison for laptops was something along the lines of 2x higher for SB ones.
Of course, since we are talking about tablets, my theory is that the SB cpu's used here will have to be clocked down a bit in order to have the same, if not better battery life.
Ivy Bridge would likely be a better solution due to it's smaller form factor though.
And I can definitely see netbooks going under because of this.
Besides, you can easily get an usb keyboard for pads now, so that solves that issue.
To be honest, I would find it very nice to own a tablet like this one, because I wouldn't have to haul my laptop along for the ride.
