Buffalo Japan comes back with the new Micro USB thumb key from the RMUM Series. I can say that this is the smallest USB Thumb key in the world that measures 15mm x 22mm x 8mm and weighs at only 2.3grams. It is actually a microSDHC card reader which is sold with a 1, 2, 4 or 8GB microSD Card. Available in black and white, the Buffalo RMUM will be released in Japan next month. [Akihabara]
