In the last 6 years with Apple making their own CPUs for OSX you could call them a vertically integrated UNIX shop. Not minicomputer though, which is from my post you replied to. Apple was not a vertically integrated vendor that survived bottom-up attack, they attacked Intel from bottom up via mobile/smartphone cores in a similar way Intel did to the minicomputers.
