Nothing wrong with the answers given. Maybe I should try a Mac some day.
Just for a reference data point, my Windows 7 PC is perfectly stable, never updates unless I tell it to, works just fine with my phone and my tablet, is just as fast as faster than the day I bought it four years ago, etc. Accept for when I upgraded to more RAM and SSDs, and on the rare occasion a software upgrade or installation requires it, I don't think I've ever rebooted it.
But I know that's not representative. Don't get me started about my mother and her PC that I have to clean up every time I go visit her. She doesn't know how to click the no-way-in-heck button whenever something pops up asking if she wants some browser search bar installed, or her system "tuned" by a web site, or if she will watch cute-kitten-video.exe that was sent to her by im.a.suspicious.stranger@aol.com or whatever.
At least with a decent Mac you're getting good components without having to think about it. I think a lot of problematic PC systems, or at least the perception that PC systems are commonly problematic, are related to the fact that a high percentage of people buy whatever cheap box that Costco or BestBuy has on sale.
I think Macs are becoming more and more popular. I'm surprised Autodesk doesn't seem to feel that a Mac version of Revit is a worthwhile investment.
