Thanks for the reply.
I'd forgotten about, mostly because I don't use them, their applications. I'd used Pages ages ago in grad school, but that's before 2013 so I didn't experience that transition.
I do realize I'm probably a bit of an outlier. I primarily use Safari, Mail.app, and a terminal with tmux and emacs. Scrivener, as well, when I'm in a more creative phase. The handful of other apps I use haven't had any problems (that I've noticed) with recent OS updates.
I will concede that, regarding hardware, they're heading towards a gray area for me. I really like the idea of the MacBook, but dislike the single connector (we'll see what happens today). And the relative stagnation of their hardware is annoying for many. But the 2012 rMBP has lasted quite well for me, I've only recently begun to notice issues with the battery life and I'm pretty sure that's because I forgot to turn off Docker (wanting to understand containers/VMs better, trying to bring my current office's development workflow into the 21st century).
EDIT: Given my relatively low resource use on the laptop, the reason I don't go with Linux is (from another post the other day), I got tired of trying to make things work on laptops. Along with rayiner, the MBP is a really solid and reliable laptop, and I want the Unix-underpinnings of OS X, without the hassle I experienced in Linux. Building a new desktop soon so I'll install linux there, see if things have changed enough for me.
