I'm often surprised that the value of OSX and its built in conveniences is not factored into a comparison. Preview, built in file extraction, TimeMachine (which does not really have any comparable alternative on windows IMO), Calendar, Mail etc.
Some of these apps are built into windows (but not with the same modern feature set) and most are available for free, but OSX seems to have hit a good selection of apps that you can use out of the box.
Edit: Also that I upgraded/time machined from my 2008 white MacBook to my current generation MBP on Lion without loosing any performance, apps or data was a remarkable time saver.
