I've been a Mac user since 2004, though I continue to use PC's at the office, I only travel with my MacBook Air that I have had since 2010.

To some extent there is an adaptation into the various idioms of Mac OS versus Windows. That's up to you to do deal with, and depends on your attitude. I saw upthread complaints about managing programs, I see it differently - managing programs is far simpler since they are better segregated and don't integrate into the Registry like Windows. You just copy it on your drive, and done. Want rid? Delete it and done. But that is my perspective since I am used to their ecosystem. if you are expecting a process where there is none, then that is a problem - but you are not wrong for expecting it. Prior to Windows 7, I would have also taken some time to say that OS X is vastly better, but that gap has gotten a lot smaller. Macs are still the kings of the "zero to productive" sprint (i.e. time from taking my computer out of my briefcase to doing what I want to do with it), and I feel more efficient doing tasks on my Mac because I am used to it, but I don't think one can clearly say Mac OS X is better the way they could with XP or Vista. Though I do think OS X is better, the difference is within the bounds of one's style.

Where Mac's DO have an advantage is hardware. They still build the best, most polished computers on the market, and, especially in laptops, where you really care about it, the gulf is big. As I mentioned, I have a 2010 Air, and I still have yet to see another person's computer I envied, even though I still get looks my way. (Edit Note: before you turn this into some silly superficial thing - this is just a way of gauging when a technology product is getting long in the tooth) Their packaging is solid, efficient, and cohesive. The two biggest advantages today: having the enormous multi-touch touchpad (and i find the various multi-finger swipes, including to Launchpad and Mission Control the biggest timesavers) and the huge battery life. I easily make transatlantic flights on one charge (I normally get about 8 hours. The same model today gets 12 thanks to some hardware upgrades a year ago.) And the package is smaller than my spiral-bound notebook and about the same weight. It's just a nicer machine to work on.

Personally - I declined my work notebook (A lenovo T series) and just travel with my personal MacBook Air under BYOD. It is just that much nicer.

For a desktop...ennh. Tougher call. I like the iMac (especially with the new screen) but I find it harder to justify. The price-per-spec comparison isn't as bad as most people make it out to be, but the problem is that Apple doesn't sell a cheap computer, or a particularly customizable one. Their desktops are beautiful, well-appointed machines, but usually for a desktop I expect a lot of flexibility that is just expensive to get via Thunderbolt. At home, having all my computers on the Mac ecosystem has certain advantages, but a single Mac Desktop...it's a tougher call. If what they make doesn't suit your needs perfectly, then you are doubtless paying for something you don't want (or not getting something you do).
