Query: Great USB storage

Wonderful little device. I now have two, one for digital photography, and another for big files that I don't need that often (i.e. e-books, installers and other big downloads). Much easier than trying to upgrade the hard drive in my notebook, and I'll be able to use them with my next computer as well. Also helpful for transferring files between computers.
