just to let you know the transfer rate on this model is HORRIBLE, even less then USB 1 (<1.5 MB/sec) speeds, even though it supports USB 2.0 which is 40 times faster. So really there is no point for the USB 2.0 support as the transfer rate is less than USB 1. Just a marketing gimmick I guess, because they know it wouldn't sell if they market it as USB 1.
For comparison, there are many types of flash memory with different speeds, but most new ones support at least 3-5 MB/s, which is 2-3 times faster then the cruzer micro.
