I was a Windows-hostage up until mid 2010.
For years I'd heard from Mac owners how great and wonderful their machines were. And I saw the figures that Mac owners were far happier and more satisfied with their purchases then Windows-computer owners. And while I was very skeptical, I decided to give the platform a go.
Well, I'm happy to say: I'm no longer a Windows hostage! Mac simply works better for all the aspects that I need. Most of the things that bothered me about Windows simply aren't an issue in Mac. For example, updating software on Mac is a breeze. Just takes two clicks and a reboot on occasion. The software is more logical, it has a nicer design, it's more consistent, it works together better... Mac has a great ecosystem for support and software as well. There are no issues with drivers, no tweaking the registry... it's worked flawlessly from the day that I bought it.
I like my iMac desktop so much, I bought a Macbook Air to take that joy with me on the road. Mac OS truly works BETTER.
If you're on the fence: just do it.
