Free Idea # 275 - PC mouse with USB data storage

Invent a computer mouse that doubles up as a portable USB
flash memory data storage device. The 'Memory Mouse' would
have a larger memory, be less fiddly to use, and harder to lose
than standard memory sticks/pens. Users would be able to
back up all their vital information without forgetting where
they left it, as - nine times out of ten - it would already be
plugged into their PC.
