Buy a Mouse for your PC!

My recommendation: On my own computer, I use a Microsoft Intellimouse Explorer 3.0. It works flawlessly with both my Macintosh computer and my PC laptop, and all the buttons can be programmed differently for each individual application. I certainly recommend this mouse in terms of comfort and precision, however I am very tempted to get the wireless version, because it fits my hand more ergonomically, especially with the thumb buttons, that are less prone to accidental pressing than on the normal Intellimouse Explorer 3.0. Of course the wireless version of this mouse is slightly heavier (and costs more too). I also use my Intellimouse to play Half-Life on my Playstation 2 (which has USB ports), and that works great. :-)
