Not sure I would trust the prototype in my lap but I think this is a good progress to laptop usability.

“The technology promises to supplement or replace today’s batteries in laptops. Instead of storing power, fuel cells generate electricity by breaking down methanol via an electrochemical process.
The cells can be recharged by topping them up with methanol from a cartridge. Recently, Toshiba, Hitachi, Fujitsu, Samsung and Sanyo, among others, have shown prototypes that suggest that the technology is just around the corner. ”
