If more developers knew what backward compatibility is, I'd be happily using Snow Leopard right now. The most frustrating part is there's nothing fundamentally new worth all the bugs and a constant envy for new hardware.
From time to time I have thought about switching to Centos as my desktop, where every release is supported for ten years. The question is, in the year 2023, will I really still want to use an OS from 2014? I’m not sure about that. In the end I think I’m really better off sticking with OS X for the foreseeable future.
