Didigo has come up with a bunch of pretty-looking, colorful flash drives. The drives feature a unique BCD (Bi-stable Cholesteric Display) that has no battery or power. The screen displays information such as the drive name, remaining disk space, and a nifty little pie chart showing how much space is being used—all without any power, so the screen still works when you unplug it from the port. It's USB 2.0 and comes in sizes ranging from 128MB all the way up to 4GB. Extremely handy if you want to throw something on it but aren't sure how much space is left. It's available now.
