Voltaic's Generator solar bag
first hit the scene at CES 2008, and it has just now begun to filter out to deep-pocketed, environmentally-friendly laptop owners. The crew over at Laptop Mag
was able to take it for a spin, and overall, they seemed a bit perturbed by the whole thing. It was not particularly ergonomic, it always fell over on itself when sitting idly on the floor and it was just too heavy to be lugged around with any level of comfort. Furthermore, there aren't enough options for laptop connectivity, meaning that lots of people will probably be left in the cold due to the limited support for notebook models. Reviewers felt that $499 was simply too much to ask for such a cumbersome device, and if two hours of extra life is worth that much to you, you're probably better off buying another battery and donating the rest to a green cause.
