Premiere/AE is taking over the industry, and he/she can get a much more powerful Windows machine for about half the cost of a MacBook Pro (which have overheating issues).
I don't think so. I think if anything, most people are resistant to CC and would rather pay once for software, making the MBP suddenly not so expensive. MBP relatively aren't even that expensive anymore. PCs will never replace Macs in the creative industry for aesthetic reasons alone unless someone decides to actually make a laptop that looks and functions as well as a MBP. Overheating issues is a broad problem. Most laptops are prone for their fans to run a lot just considering all that's packed in there. If anything I've found that the fan runs less on my MBP than any other PC laptop I've owned.
No pro video editor I've ever met buys a laptop or desktop because it looks good.
CC is annoying, true, but there isn't really another option out there except piracy without the option to update. FCPX is not professional editing software, and AE/Premiere are leaving the older version of FCP in the dust - it can't even export mp4s without the user tricking it! $30 per month for the whole Adobe suite isn't so bad, really, which is exactly what Adobe is banking on, but still.
My ($2500) 2009 MBP burned out last year and I upgraded to a ($1150) Lenovo laptop with 16 gigs of ram, an i7 2.6ghz, a 4gb NVIDIA card, native 1080 display, and a 512gb SSD. I could barely edit in FCP on my MBP toward the end, not for lack of taking care of it. AE is blazing fast on my new Windows machine, about the same as a specced out 2014 iMac I was using at my old job.
I was really, really resistant to switching to Windows and essentially learning new software - I was faking AE pretty well in FCP! - but it's where the industry is heading, since Apple is targeting consumers far more than pros these days.
