I too used to be one of those guys who ridiculed Mac users for having bought a computer that was 3 times as expensive as a PC.
Then, in 2005, I got a job at a movie prop house in North Hollywood, CA. I found out that most people who work in the entertainment industry use Macs, and I hardly ever see a client using an Android phone. As I casually caught glimpses of clients' Mac screens, I became more intrigued with the idea of Mac. They kept telling me how wonderful Macs are, how virus- and malware-free, and that I should go to the Apple Store to try one out for myself.
Well, I *FINALLY* did that this May - I went into the store and played with one for about an hour, and asked the very helpful "Blue Shirts" many questions. I went home to think about it some more, then ordered a refurbished MacBook Pro retina 15" from Apple online. I received it the next day, and I keep asking myself, "Why the **** did I wait so long!???" My only regret is that I didn't pay extra to get the 750GB SSD storage option - I have 250GB. But I've worked around that by keeping my entire iTunes library on an external HD (which isn't bad, since I listen to music almost exclusively on my iPhone 5 or iPad, and usually only connect the drive to perform iPhone and iPad backups, or to watch the occasional movie).
I run Windows 7 on it as a Boot Camp partition, because I have a few old MIDI and music synthesizer control programs which only run in Windows, and also a couple of older Windoze-only games.
