I wouldn't say I'm so fixated on the escape key that nothing else matters. The base OS matters a great deal! I pursued three lines at this particular fork in the road, I considered buying a 2016 MBP, a refurb or whatever, I considered switching to unix on whatever hardware (leant toward dell XPS), and I considered a windows box, with unix living underneath, somehow. The first option just seemed crazy to me, perhaps irrationally, but making my new machine a two year old machine just felt wrong, the second option could have mostly worked, except that I really need excel, and I really want ableton. I decided to give the third option a try, thanks to the money back guarantee, and I'm amazed at the improvement.
I suffered the temporary pain of switching to OSX in '06 because I'm not religious about these things, and at that time macbooks running OSX were providing an exceptional environment for devs like me. It was a hard transition, but after a couple of months I was (mostly) fine. A fair amount has changed in the world in 12 years, and I'm no longer convinced that OSX inherently provides the best environment for a dev. I figured give windows a shot and see how it goes. It took me 24 hours to get the machine in a state where I could work as before (this would have been impossible on a windows box in 2006), and the question now becomes, why would I go back? It's only been a week, so perhaps windows will show me why very soon, but my gut feeling is it won't.
Also worth considering, is that from about 2000 onwards, apple was catering to open source focussed devs, at the exact moment that microsoft was making their lives impossible. I think that trend may have been reversed. Every upgrade to OSX for the past six years or so has represented more pain than pleasure for me. YMMV, but microsoft's offerings, even when flawed seem to be headed in the right direction.
As far as the comment, yeah, I was a little snarky I suppose, but a common response to complaints about the lack of an escape key is "you don't actually need one". I'm sorry, but I do. Ok, I don't need one. but I really want one, and this is a laptop we're talking about, and I use it as a laptop most of the time. I also want ports, a headphone jack, etc. But the escape key is for me the last straw, and enough of an incentive to actually look on the other side of the fence, which I've avoided doing for 12 years. I like what I see there.
