The first computer I owned was the original 2005 Mac Mini. My second was the early 2009 Mini, which I am still using, currently running Mountain Lion. My next will be another Mac Mini, in a couple or three years, I guess.
The experience has largely been hassle free, compared to the Windows computers we have at work, which seem to be constantly in need of attention to the software or the hardware. Cheaper they may be at initial purchase, but over time that seems to be false economy.
I got a computer to do things, not to tinker with, or to brag about having the latest, fastest, prettiest or whatever.
In my experience, dating back to the original Mac that I used at university in the mid '80s, Apple computers just work. Admittedly I had little to do with computers of any kind in Apple's dark days of the 90's; my days then were spent driving tractors, building fences, and shearing sheep.
The only real hassle I have had was when I bought new to the market Xerox printer about six years ago, and had problems getting a driver for it. The shop I bought it from was no help. The Xerox people phoned and told me to pop in to see them at Panthip Plaza….. over 900 km away! The local Apple dealer found and e-mailed me the driver. Their sound advice, and prompt service, must also be a factor in staying with Apple.
Microsoft Office may have more features, but the iWork I use on my Mac Mini has all that I need. I do also have Office for Mac installed, but seldom use it. Any Word documents that come with Thai script doesn't open properly for some reason, but they open just fine in Pages, and re-export just fine converted back to Word.
The only other Apple product I own is a wired Apple Keyboard, which I like. I'd be tempted to replace it and the wired Logitech mouse I am using, with the Magic Keyboard and and the Magic Mouse 2 when I replace the Mini I am using now.
I live a simple life, so have neither need nor desire for any other iDevice to complicate things.
