System 9 still lacked preemptive multitasking, due to a pragmatic decision from the very beginning of MacOS. (Perhaps even predating the Mac?) That alone would be enough to say that it was showing its age. As someone who was using System 9 at the time, I would say that this is indeed what knowledgeable users were thinking.

It's not entirely true. Copland microkernel was in (hidden) in System 8.5 onward, and provided preemptive multitasking, file mapping, timers etc. It's just that the only real 'task' on it was the old cooperative OS.

They had made a LOT of work on that, and the driver model by the time System 9 arrived. What really failed on Copland was the 'userland' equivalent. At the time, Apple had gone into a completely bizarre way of designing complex APIs for everything and most of them had no use whatsoever. There were heaps of crap, like OpenDoc and many others and Copland was 'trying' (and failing miserably) to integrate all of that.

How do I know? I have a collector t-shirt with 'Copland Driver Kitchen' on it ;-)

8.5 wasn't released until years after Win 95, though.

Slight correction: it was called the "nanokernel".

So not entirely true -- it's "only" true from the standpoint of typical User Experience.
