I hang out a lot in internet cafes these days, and I noticed that while most customers have classy laptops, sometimes, they also have really crappy (and wired) mice! If you happen to have a friend in this situation (I do), the Logitech VX nano is a great gift. This mouse is most appreciated for its ergonomic shape, the nice wheel feedback and most importantly, the uber-small USB dongle that is small enough to avoid accidental pressure on the USB port. $50
