That is what made Sun, Digital, and SGI loss hurt even more. Dell is nothing in comparison, just a bargain box maker with no ambitions beyond. Losing those other companies hurt because when you control the hardware and the operating system software, you potentially can build anything.
Look no further than Apple computer. I must admit, back in the day I wanted a Next computer or an SGI computer because of the graphics and sound capability, but the only thing I could afford at the time was an Amiga computer later on, I had to settle for a work related Microsoft computer using AutoCAD, Revit, Navis and a few other graphics programs.
