Remember this thumbnail-sized USB drive by Buffalo? The company developed the idea further with the RMUM-H, which, not only packs up to 16 GB of data in its thumbnail-sized package measuring 11 (W) x 15 (H) x 1 (D) mm, but also holds a Micro-SD/Micro-SDHC card reader that expands its capacity. The card reader can be used to port data between compatible phones and cameras, and the PC. The 16 GB variant (RMUM-16GH/BK) is priced at 10,900 JPY (US $112), the 8 GB one (RMUM-8GH/BK) at 5,200 JPY ($53), 4 GB one (RMUM-4GH/BK) at 2,600 JPY ($26.5), and a 2 GB (RMUM-2GH/BK) variant for 1,700 JPY ($17.5). There is provision for a lanyard or keychain, which is very much welcome.
