The multi-readers get smaller and smaller, and this iMono SIM card packs more versatility into a small form factor than we've seen yet. It handles a veritable alphabet soup of flash memory cards, including miniSD, all types of Memory Sticks, microSD, SD, MMC Card 4.0, MultiMedia Card, MultiMedia Card Plus, RS-MMC (MMC Mobile), RS-MMC4.0 (MMC Mobile 4.0) and MMC micro. It also reads cellphone SIM cards. Plus, there's no cover to lose.
I picked up a reader similar to this in Singapore recently, and it's functioned well enough to find itself a permanent place in my road warrior's bag. Not a bad deal for $19.
