Flashbag USB Drive
The design is still in its conceptualization stages, though and I’m sure that at this point, people would have mixed reactions about the drive. For one thing, I think it’s pretty silly to have to use the thumbdrive’s size as a visual cue for free space. I’d have some difficulty fitting that one in my pocket in its expanded form. I’d rather have an OLED indicating the percentage of occupied space. But I guess it’s exciting to see the disk expand and contract as you add or delete data. I’m also pretty sure some people would find more creative and imaginative ways of using an expanding-contracting mechanism.
