Why is SGI a bankrupt company today?
Why is SGI suing ATI but not Nvidia?

Answer - Microsoft got then-CEO Rick Belluzzo to give away SGI's crown jewels graphics patents and graphics engineering team to Nvidia for free... Belluzzo's last act before jumping ship to Microsoft. One more "dirty trick" in the Microsoft portfolio.

I swear after the fall of SGI, that company is only good for one thing.. the same as SCO...

Bankrupt company becomes litigious proxy for big monopolist. I think I've seen this before.
