This is a great little concept and SanDisk have succeeded in creating a 32GB device with dual functionality. Doubling up as both a standard USB drive and one that is compatible with your smart phone, this is sure to come in handy for those who rely heavily on their phone - a number that is bound to increase as our phones become smarter and us more reliant upon them! I must admit that I have tended to mostly use this as a standard USB drive but then I am more computer based than phone based. The dual functionality is, however, a great bonus which is sure to come in handy with my new phone. The one problem I have found so far is that the protective sliding caplets (the ends remain open and not totally covered) slide back too easily meaning you may as well be storing this in your pocket/bag without any protective covering at all. That being said, I own other usb drives that have no covers at all so at least this has something that affords some form of protection even if it isn't perfect.
