Apacer's Handy Steno AH421 memory stick comes from an interesting angle -- getting the "stick" part out of the way, so it can sit flush with the device it's plugged in to.
It's smarter than just putting the stick at right angles though -- the body can rotate through 180 degrees (clicking into place at 0, 90 and 180 degrees), to make sure ports don't get blocked. It even has a clothing-style tag on the side opposite to the USB connector to make removal easy.
Where the Steno falls down hard though is it doesn't take recessed ports into account, meaning it simply won't make sufficient contact with some PCs, no matter which way you rotate the body. Other companies include a USB extender cable where this can potentially be an issue -- Apacer does not.
The AH421 is certified for Windows Readyboost, and the sustained read of 23.4MB/s means it's fairly speedy too. Unfortunately it's a bit hard to overlook the recessed ports issue.
Apacer's Handy Steno AH421 is available in 512MB, 1GB, 2GB and 4GB capacities.
