I switched a few years back. first with my laptop via a macbook g4 runnin tiger. that whetted my appetite for mac and allowed me to realize the potential of the platform as a development environment. ultimately i moved my entire development operation over to a mac pro tower loaded up with 16gb ram and a few tb of space specifically so i could develop on whatever platform i wanted through the use of virtual machines.
for most of us that are doing web oriented software development, the ability to run multiple versions of client side browsers not to mention multiple versions of server installation through a virtualized environment is a major boon to productivity. if as a developer you are researching a platform to use as your main development you should really take that into account. if you are a device driver developer or working closer to the hardware thats another story.
also, ask yourself: are there any developers contemplating switching to windows?
