When Will Batteries Last A Week?

Like many of you, I'm constantly on the look-out for wall outlets. Meetings, airports, etc - if there is an outlet, I'm trying to find it. I've always fantasized about not having to carry around a charger. Wouldn't it be nice to get 40 hours out of a battery before having to recharge? It sure would! When will it happen? Lenovo has an interesting infogram out that take a look back and look forward when it comes to battery life technology.



Looks like we've got about ten years to go!
