There are all kinds of USB drives out there: cheap ones, simple ones, ones shaped like fruits or vegetables or sticks or engines, ones that can run software and ones that dare you to drive a car over them or drop them in the Marianas Trench to see if they survive. The Memorex M-Flyer, however, is the only USB drive I've seen that replicates the simple amusement of a click pen in flash drive form. That's right: along with its sleek, unchallenging design, ReadyBoost capability and up to 4 GB capacity, the M-Flyer includes a spring loaded, cap-less design, so you can secure the drive's connector from damage without worrying about losing a cap. Of course, because it's spring loaded, you can spend hours pushing it into the drive and popping it back out. Think of it as another way to annoy your coworkers.
