It's a fact: in the world of storage capacity, bigger is better. But when it comes to portability, small and light is the way to go. Hitachi's new Microdrive 3K4 digital media marries its go-anywhere size to 4 GB's of record-it-all storage. No bigger than a matchbook and just as light, the Microdrive will fit 75 hours of high-quality music into the change pocket of your jeans. Or swap out all those songs for a DVD movie. At 4GB, it's four times bigger than its predecessor and much more economical than standard flash memory. More capacity means more photos, more music, more data, more possibilities.
