Apple used to be famous for bringing out new libraries to "revolutionize" computing, hounding developers to become dependent, then dumping them after a few years when they didn't get mentioned enough in the press. Lots of us from the Classic era got burned by embracing the uber-hyped QuickDraw3D or OpenDoc, for example.
Now Apple seems to be keeping (mostly crappy, the last 15 years) software around, and abandoning hardware that doesn't make them immediately rich. Progress?
I got into Macs around 1985 and refused to work on anything else through the early 2000's, when things got so bad that it stopped being fun or practical. I got rid of all Apple gear, spent 20 years working on Windows, and mostly enjoyed it.
