I have used Windows since the XP days, and just shied away from Mac OS as I only ever encountered it rarely, and I told myself it was bad, because it wasn't what I had. So childish! A few years ago I had the option to choose a PC or a Mac as my laptop (as a present from my parents), and I foolishly chose a PC, while almost at the same time my brother got a Mac. Now, my Windows PC crashes pretty much twice a week, and it insists on pretending it has never been connected to our home Internet, so I have to manually reenter the password every time it crashes (Our password is over 30 characters long, and is completely meaningless). All this while taking 10 minutes to start up, and just being generally bad in general.
Contrast this to my brother's Mac, which runs incredibly smoothly (he says it has never crashed on him), starts up in less than 30 seconds, works flawlessly with our internet connection, and comes with Siri, FaceTime, iCloud (for photos and music), and iMessage included. I could kick my previous, foolish self.
Oh, and price isn't even much of an issue, my brother got his mac for only about 15% more than the cost of my HP Envy.
So basically, I use Windows, but plan to jump ship as soon as is economically viable for me to do so.
