For all laptop users you must have felt what I feel ! The autonomy issue that all mobile computers users are bitching and moaning about. The laptop batteries are an obstacle to fullfill the meaning of a mobile computer because you will not be able to spend the whole day without charging you laptop's battery !
A little hope .. we heard about Intel and Panasonic working on a 12hour battery two years ago but still see nothing on the market..
Instead of being a part of a crazy race of speedy processors I think that hardware constructors should have taken care of autonomy issue and be closer to satisfy the user's needs.
The American military technology laboratory has made a new invention which is a 30 years continuous power without a single recharge ! Using semiconductors and radioactive materials an energy source. So this is an extreme solution because people don't want to be infected by their radioactive laptop battery. I think they will stick with the electric wire !
