Big deal...Fry sells a hard drive enclosure that has lithium rechargeable batteries to power the hard drive. It also has built in card reader on there. There is a button on the case for copying contents on the memory card to the hard drive without hooking up to any device. It's less than 100 dollars. Thought about getting it for the nokia 770 but I haven't found the use yet. I got a 1gig card that hasn't filled up.
