I also have the Tron motorcycle flash drive. These were picked up on sale and used occasionally for booting one of the many bootable OSes. Domo has a copy of the TAILS OS. Makes it easy to spot in my bag of flash drives.

I buy flash drives all over the place, like in bundle deal or run to the local shop and get one. These in turn become either the customer's, left with them after reimbursement or to lug my files/pgms., I deem necessary plus a immediate storage media.
I really don't buy super cheap or those that look too cheap. While, I'm willing to try a different brand now and then, I stick to some brands having proven themselves. I brought Kingston, in small metal case and able store easily. However, too often I forget and leave a flash drive behind to retrieve later, thus I tend to buy "colorful flash drives" and attach a leash of sorts in order to remember. I also look for so-looked tough or ruggized flash drives. Here, I think I found one that states it is one, the Gorilla "ruggized" drive. It sure looks to be tough, being rubber coated, sealable cap(up to 65ft.), and metal loop to leash. So far, its done its job and appears to work in typical applications. I just thought to offer what works for me.
No, I haven't brought bullet shaped, cartoon character, or gadget flash drives, but they do look neat.
