^^ I'm perhaps an odd-ball. I push my platforms to the limit as part of what I do for a living.
I also had a company where we used VMs for every version of every MS OS including the servers, so my perspective may be relatively unique.
And I worked for a few dozen clients, large and small, delivering packaged and custom software plus SaaS, so that provided a zillion 'OMG' moments across desktops, servers, databases, browsers.....
Now, that said, leave your PC on and let Windoze update do something, even just notify. But for Win7, and even on the server editions, I assure you it will take a dump.
I still love 'em both -- PCs I do have more software choices, and I can coax anything to work, eventually.
Mac is closed loop, so if it runs it runs.
I guess it is more like who you date vs. who you marry. Different strokes.
The best part of it all is that now HW is so cheap that we could all have both.
And that you cannot do (legally) with a spouse.
