Unless of course you want to talk scalability. While at home I use Linux, at work we have 64 proc E10K's and 128 proc SGI's. While I love linux as a workstation/departmental server, for the scientific community Solaris/Irix are the best choice right now. Unfortunately, at this time linux does not scale as well as Sol/Irix on a single system. I am hoping that linux scalability will reach the levels where I could replace Solaris7 on my E10K with linux but until then Solaris is still the only choice.
Hotmail runs(ran) on Solaris. Not sure if they still are or not.
