Hi, I am sure many of you have either seen or perhaps own the relatively new portable USB devices that can are small enough to fit on your key chain, yet have enough memory to carry around tons of essays, photos or music (depending on the amount of memory available - 64MB to 512MB). So, there are a plethora of companies out there - Sony, Iomega, Samsung, Lexar, Toshiba - as well as some independent companies. Does anyone have any advice on what to buy? What models have people dealt with that have proven to be reliable? Reasonable price? Was the version small enough so that is wasn't a pain to carry around? (If you want to see a ridiculous "portable" USB, check out Sony's 1st version of the microvault; it's huge. I appreciate your feedback and hope others can benefit from it also.
