Gee, todd. You must be president of the I-Love-Bill fan club
What I, personally, have against Microsoft is, firstly, their blatant disregard for patents, contracts and copyrights, and secondly, their attitude of domination in the marketplace. When you turn on your X-Box, turn that second thought to the fact that they tried to buy Nintendo. And that the X-Box is still a gigantic loss for Microsoft. And when you turn on your PC, let's not forget the broken contract for MS-DOS, and the dodgy dealings with Apple that led to Windows being released so close to the first Macintosh OS.
It's only natural that Bill would spend so much on charity. He has more money than is possible to spend, lives in a robot house, and has a nasty public image to save.
