Yes; I'm looking back at my "mac fanboi problems" from the 1990's, and the reason I bought Macs then, was to run Mac OS, or some mac-only software - the hardware was always pretty much playing "catch up". The fishtank-iMac was the first glimmer of hope on the hardware front. The dual G5 was amazing, even if OS X was kind of rough.
But at a certain point, it became obvious that the OS team was being pillaged of talent for the i-device (iOS) team. The fact that Apple pulled all support for PPC kind of put a knife in it for me. And that's when I went over to PC hardware.
Windows 8 was an amazing opportunity for Apple - and they totally blew it. Microsoft tripped, stumbled, and Apple could have curb-stomped them with a great development effort to tune-up OS X. They blew that opportunity off. And Microsoft STILL isn't really on their feet yet.
Now: I have a macbook pro - because it's just an "insanely great" piece of hardware. But the ONLY reason I'm running OS X is to be able to use VMWare Fusion. If VMWare Fusion's features were available on Linux, that's what I would be running on my MBP.
