The curtains go up, and it's a monster (battery) mash:

The Air's 3.73 V, 32.9 WHr, two-cell power plant is decidedly less monstrous than the previous iPad's 43 WHr, three-cell behemoth.

Despite the iPad's skeletal slim-down Apple claims that, due to an increase in efficiency, you can still watch the Great Pumpkin at least 20 times in a row.

Ogle all you want, but this battery isn't coming out…yet.
