I think the point with the battery life comparison is this:
Tablets are intended to be used away from a desk and away from an AC point.
If you can only use one for 4 hours like that, it is not really a usable device for people intending to work like that all day no matter how mobile it is.
The iPad can do that. A laptop can do that.
