Most mice are a pain in the neck to use on uneven surfaces when you are traveling with a laptop, but this sweet black tiny USB mouse is a simple pleasure. $29 bucks gets you a terrific, small, well designed optical mouse you can take with you, sporting every feature you would expect from a full size mouse. What more can I say: it works wherever you need it and it's so much better than the feeble pointing devices built into the laptop that I find awkward and largely impossible to use.
