I'll lose this one as well

USB memory sticks these days are lost just as easily as a Bic ballpoint pen. Furthermore they're likely to be 'nicked' more often than your pen. The problem with this USB stick is that it will be trown away more than anything else because it looks like something you should throw away. Leave it on your desk after working late and the cleaning lady will toss it in the bin. I suppose it's some kind of security.
