I vouch for RizXiv when they say how amazed they are at the MobileMate Micro Reader. I got one with an old 8gb MicroSD card last year and the transfer speed is so much faster to use than using the memory card reader from, lets say a camera or something.
I've got mine attached to my phone so I always have it to hand whenever I need to get music, pictures or videos off my laptop and stick it into my phone.
Worth investing in one of these instead of relying on using data cables with your camera/mobile phone and having to faff with installing software.
Also the icing on the cake is it's M2 card compatable as well as SDHC MicroSD compatable.
