I feel you on ALL of what you just said. I'm a freelance motion designer and teach in a college motion graphics program. I feel like the Apple ecosystem is as strong as ever but the hardware is just getting to be kind of eccentric. It does some things so well and might abandon other things altogether. I'm so deep in the ecosystem it's just insane. If you saw me type this from my classroom you'd laugh because I'm surrounded by so much Apple gear it's ridiculous; Mac Pros, iPad Pros, MBPs, Watches, Pens, and exactly 1,000,000 dongles.
But after days of benchmarking, I'm just sad about the performance. I have 2 nice 2009 Mac Pros (in my signature) that along with an HP z820 allow me to get some serious work done at home, but at this point I might end up with the same 13" MBP you have and an HP Zbook in my bag for heavy lifting when out and about. Can't believe I just said that.
I mean when I think about it, it makes me mad, then sad. OS X was and still is such a solid operating system. There have been times when I was working doing digital composting, coloring, editing(final cut pro-NOT X), working 14 hour days, and my MacPro tower, or my MacBook Pro with OS X would never crash!! It would always boot, everything would always work. It just "WORKED". It was incredible. Everything was so rock solid. Also I used to compile little Linux applications that no one else on the PC had.. Stuff some guy from ILM or PIXAR wrote in his spare time to make his life easier, and It was awesome.
Then when I would jump to Windows it was like yeah, not so much, the same hardware, but every vendor has different drivers, and plugins and what nots, it just made it so scrappy, but not in a good way. Microsoft never made it easy either Constant updates, constant bugs, constant malware warnings.
I do have a Windows10 tower, and its fine, some of the FONT rendering and stuff drive me nuts, and I think it needs more refinement like OS X. And if its just windows, adobe and nvidia its fine, but drivers and updates constantly happening are very annoying.
When my tower dies at work they want to get me a Z100 or whatever HP makes as a high end tower at the time, and switch our grading theatre to Windows from OS X.. It will be sad when that happens, but apple totally abandoned my market.. so what can I do.
