It is perhaps too early to wave goodbye once and for all to that coalition, but it does seem like some of the design directions that Apple has taken have drifted away from that user base.
That said, this war on the professional and creative class of users began sometime ago - I think the introduction of Final Cut X was the first salvo, while the platform has significantly evolved from the first couple of problematic releases, I personally know some who considered the product a literal betrayal and abandoned ship to Premiere Pro or AVID.
I sense Microsoft is attempting to reassemble that coalition with their offerings, namely the Surface line (especially that gorgeous looking Surface Studio) and the introduction of Bash on Windows, which while still quite limited in its functionality, can be a seen as a step.
I really like my MBP 2013 (NVIDIA GPU) and I guess I am going to keep it a while longer.
