Re: Sentiment vs reality?
Also agree that 10.6 was the peak OSX release. Significantly it was also Bertrand Serlet's* last release as head of OS development. He left Apple after this release, handing over to a guy who'd only been in the company a wet weekend. The next version, 10.7 was the first ever MacOS X release I rolled back.. But it wasn't the last. My Mac is still on 10.9, and I think it'll retire on it.
(* An ex-NeXT manager who led OSX development and later took over as head of all software. The most senior person I had a proper conversation with in my time in Apple: I had a somewhat heated engineers' argument about application resource formats with him, *before* my then manager revealed exactly what his role in Apple was. Oops.)
