Mac User since the 80's. Have to be Windows conversant at work, though. Plenty of people I meet assume the two are not compatible and are surprised to find out how similar they are.
For work and online school, had to buy XP and Fusion, works just fine for work and for school, since it's all thru a browser, I used the Mac only for the last two classes, no problems at all.
iPhone also in use and everything swims happily together. So much that we do these days with computers is platform-independent, why not get the machine that is nicely designed and is much less a malware target? And can be two computers in one. Almost no reason not to go Mac these days.
