Not a bad idea this: A pen with a built-in USB drive. PNY Technologies have just launched a line of Executive Attaché ballpoint pens with attached USB 2.0 flash drives that hold up to 512 MB of stuff.
The pens look chunky — and very executive-looking, ‘made with -quality materials similar to those of high-end writing instruments’, and in colours ranging from blue and black marble to black and red herringbone to brushed silver — but not unpleasantly so. The USB bit is basically the top half of the pen, which when removed reveals the USB plug. They cost between $80 and $100.
