Either those or some pretty dang huge keys, or this new USB Micro Drive for microSD
being sold by Brando is most likely "the world's smallest microSD reader" it claims to be. There really isn't a lot to know: it runs at full-speed USB 2.0, measures 5mm thick, weighs a tenth of an ounce and reads microSD cards. With this kind of size, you could just leave your microSD card inside the $14 reader for a DIY thumb drive, or use it as a card reader all normal-like, but that's about all that's going on here. Fire this thing up with one of those fancy new 4GB microSD numbers
and watch the sparks fly!
