I switched from Linux to Mac in 2003. I had a laptop stolen, and really liked the idea of a slick PowerPC laptop running Unix. I figured if I didn't like OS X, there were several PPC linux distributions I could choose from.

Three more Macs later, I don't even think about it when buying a laptop. I've seen fink mentioned above, but I prefer MacPorts. Its great to see where things have come in the last few years.
