I had a similar path, from MS-DOS 5 / Amiga OS point of view, something like SGI seemed great and I dived into Linux zealotry a couple of years later.

But then a rich library at university campus opened my mind to other models of computing and sundenly pure old UNIX wasn't that interesting any longer, only NeXT, which used UNIX compatibility more for winning over Sun's customers than anything else.
