Everyone needs one. Well, everyone who routinely washes their thumb-drive or cell phones in the washer & dryer (honey, what's that thumping sound, oh wait, it's the cell phone). My current thumb-drive has been washed once (its rubber and can take a beating), my previous one, amazingly, survived something like four washes; i don't remember who made it, but i gave it to all the guys in my wedding. Maybe they still have it. Alas, my cell phone, washed this weekend, didn't hold up so much. I'll have to buy a better one. They should really stopping making such cheap crap; can't even withstand a little water, heat, extreme turbulence, soap...
