The basis of my comparison was nothing to do with business circumstance, but just that Apple and Oxide both were known for having taste in software (in Apple's case faded but still apparent in the DNA), and they build their own hardware to express that taste.
I think perhaps Solaris had a bit of that under Sun but I can't imagine that being the case under Oracle. And I'm not really an enterprise infra guy so can't really speak to IBM or Unisys offerings.
