True, also before, during, and after the Intel transition the ecosystem of indie and boutique apps for Macs was great. Panic and The Omni Group, just to name two boutique development companies, were probably at their peak in terms of desktop software. Besides, Mac OS X Tiger, Leopard, and Snow Leopard were polished and the UI was usable and cohesive.

Right now, the quality and attention to detail have plummeted. There is also a lot of iOS-ification going on. I wish they focused less on adding random features, and more on correctness, efficiency, and user experience. The attention to detail of UI elements in e.g. Snow Leopard, with a touch of skeuomorphism and reminiscent of classic Mac OS, is long gone.
