There seems to be an endless stream of reuses for keyboard keys but I don’t think we’ve ever seen a USB card reader made out of them, so here we go. This four slot card reader uses the control and enter keys. The control key is just a cap for the USB plug. This reader supports a whole slew of formats including SDHC 2.0, SD, micro SDHC, microSD/T-flash, Sony M2, Memory Stick, and MS Duo. It supports Window Vista/XP/2000 and Mac OS. Pretty cool and it comes in dark blue or white.
