True. (Though laptops _are_ getting smaller, along with their batteries, but not all that much.) Moore's Law covers a few aspects of computers, or at least approximates to their growth rates, but significantly, not to others: memory and hard disk capacities keep growing rapidly; their access speeds lag somewhat. (Also: Number of users on the internet probably Moores (if that's a verb); their average cluefulness does not, as can be seen by the great number of stories of computing stupidity around the place ) Batteries get their occasional jumps, like this, and not all that much in between.

Actually, if you look at the mAh ratings on the batteries, you'll probably find that they've been increasing or at least steady, while the physical size has been shrinking. Maybe not at the rate of Moore's, but there has been improvement, and yet not in actual life.

Side point: Emirates have a brilliant service: You can charge your laptop battery on the plane. Yay! And that's not just in business class, either, I enjoyed the privilege in economy too. Now THAT is the way to extend battery life!!
