> HP's HP-UX hardware being an exception since they just sloppily hacked in standard ATI cards / which means you wouldn't get the extra benefits of running a GXT6500 on AIX as you would with a FireGL X3 on HP-UX. HP probably had the lowest share of the UNIX CAD market so they probably felt little need to invest much R&D: not to mention HP can't make a proper enterprise workstation or server ANYWAYS.

As the kids say: LOL.
