Multi-card USB readers - why is this concept more well played? It IS played though, even though it might not be well spread. Here's a couple for you from Elecom, available in Japan (or over the internet through GeekStuff4U, which is in Japan too, but online, and online is everywhere!) One is the multi-card stand-up reader MR-C27 which reads up to four SD/SHDC or SDXC cards at a time - supporting cards up to 64GB. The MR-SMC06 is a dual-card USB stick or thumbkey which has no internal memory in and of itself but has two microSD or microSDHC slots. Super cute and super handy!
