The new iPad looks very similar to the iPad 2, in fact its so hard to discern it from the old one. But on the inside, its got guts that are pretty nice. Finally the 1GB of RAM to accelerate all that web browsing, but the most impressive thing is its 70 percent larger battery.

The iPad 2 had a 25-watt-hour Li-ion battery. The iPad 3 has a 42.5 watt-hour battery! That's 70-percent more than the previous capacity.

The battery life hasn't changed, however: it's still ten hours of use, nine with average use of the cellular data network. [ifixit]
