I moved to the light too
I switched over about 4 years ago. I like OS X's simplicity and reliability, I'm not battling with the operating system, as I was with Win XP and Vista, just being more productive. The analogy I'd use is cars, when you are young with heaps of time on your hands, you can enjoy restoring a banger, repairing old cars that you could never afford to buy brand new. But as you get older, you'd rather not spend your time on the machine, but just want to get from A to B quickly, safely and in comfort. Same for computing
I got sick of windows hanging up, and crashing, trashing hours of work. Programs that just stopped working. The constant threat of virus and malware, and the reality of it at work, when idiots merrily open all email attachments regardless of origin. Funny thing is that I still use Win XP for my CAD system run under Parallels, and guess what? Win XP is much more stable on Mac hardware.
I was visiting a customer last week and during the meeting there where two occasions when their windows laptops crashed or hung up. I was so glad that I no longer use Microsoft products, but what truly amazed me is their acceptance that their 21st Century computers crashed and hung up, they even congratulated themselves on managing to restart and "solve" the problem.
We all make choices in life, guess a lot more people are choosing a Mac. (Resale values are higher too)
