Some other company bought them (Rackable Systems) just for the name and are selling products that are not anywhere near as cool as the old SGI products, but are still considered super computers and big storage.
I do miss SGI. They had really cool workstations. Expensive as hell. We had to lease them instead of buying them.
Besides doing actual work, remember playing and compiling a bunch of OpenGL demos on them. Even found the Jurassic Park file browser, by accident, and only years later connected the two when watching the movie the 2nd or 3rd time.
I remember the "onslaught" of Windows NT and Windows 2000 workstations with larger, beefier graphics cards, more memory and faster processor. I could tell it was the end for SGI. But I will always remember them fondly.
