They used to be cutting edge innovators in the graphics world - I remember them visiting my uni in back in 91 and giving a demo of some military spec system which had shading, texture mapping and lots of other goodies which I personally didn't see bettered in the consumer market until almost 10 years later. These days however SGI seems to be little more than another Intel box shifter, trailing behind Nvidia and ATi in the graphics market and making little impact in the general server market. I'd be sad but not surprised if it didn't last very much longer - either going out of business or being bought out for whatever useful intellectual property it has left.
