I came across this 160 Mp camera today. A real digital replacement for the film 6x17 camera, yielding a 950 Mb file (uncompressed) for the full 6x17 format. At 30k Euro, I don't imagine I'll be getting one any time soon - but it's a damn cool idea.
On a more affordable level is the rather wonderful USBCELL which produces a AA rechargeable battery which has a flip off head to reveal a USB socket. So you can recharge the battery by simply plugging it into a pc USB port. They have plans to produce specific versions for mobile phones and cameras, which would do away with the swag of custom battery chargers we all have to carry around.
