buy them online here or at Smiggle shops. They are only 2GB for $24.95; but that's enough for daily working, and the convenience factor is part of what you're buying - I know some of my flash drives have had tiny lids, very easy to lose . An idea for kids, too (and don't forget to remind them that the only copy of their brilliant work shouldn't be on a flash drive and nowhere else - they are transit devices, not permanent storage).
The other Smiggle electronic item which combines cute with useful is their hub. Most USB hubs are drably functional. How about a turtle hub?
$19.95. Buy them online here, or also at a Smiggle shop.

PPS. You can blame the gadget gene that runs in my family.
PPPS. Also that I am bored with trying not to lose tiny flash drive lids from cheap flash drives. I know, I should get the ones with attached/swivelling lids.
