I've been using a Macbook Pro for about 10 months now. My wife has been using an iPad as her primary computer since December. We don't use iPhones, but do have a couple of Android-based devices that we occasionally use.
Bottom line is Apple products are awesome. They're the most well-built, responsive, and intuitive machines out there. (One exception: Every time I actually am able to load a program on my Mac, I feel like I just got lucky. Of course, I have never not been able to load a program ... so maybe that proves something right there?)
As a photographer, I knew it was only a matter of time before I had to go Mac. The entire world of photography is Mac-driven, and I can't imagine that that is ever going to change. Funny thing is, I don't actually dislike Windows. Windows actually feels more “open” to me, if that makes sense. I feel like my Mac is tightfisted with my files. In other words, my Macbook Pro thinks my files belong to it, not to me. Just kidding. Sort of. Not really.
About Android. Not impressed. I mean, it's sort of meh. It's alright. Not as responsive as iOS. Sort of a wannabe. But what do I know? I still use a dumb phone. ;-)
