The collected works of LionRampant

Greetings, all! I was wondering what some of you have for reasons you choose to own and/or operate a Silicon Graphics workstation or server system--instead of, or in addition to, Windows, Linux or Mac systems (all of which I currently use). Does anyone have compelling reasons for owning and using SGI hardware and OpSys software?

Neko's been tinkering around with his SGI systems for years, and I haven't seen a whole lot of reason to head down that path myself. So, why do you use SGI? Use them at work, or enamoured with the "SGI mystique", or because at one time these systems cost huge sums of money? Do they outperform similarly-priced systems based on other architectures? Is the OpSys design and implementation far superior to the other options out there?
