>> Mac hardware is great!

I think that depends on your view. IMO, Apple generally does make some of the best hardware in terms of quality and design, but there are exceptions.

The Mac Pro garbage can, for example. I don't know why they chose to make an art piece to replace the incredibly functional and expandable tower that existed before.

Another example is the early 2011 Macbook Pro 15" with discrete GPU, which had serious overheating problems that they just pretended didn't exist for more than three years.

This goes against my (and others) experience. Every recent OS release, Apple has dumb'd down the UI, not just for devs, but any user.
