[NTSysADM] What is the argument for Windows Server Core/NanoServer over Linux?

[Katherine M. Moss]

Hey all,
Just had to ask this one. I'm really curious because I've heard the argument, 
well, if you're going to run server Core, why not just use linux? What can you 
say to make the conversation worthwhile and not just arguing preferences? Or is 
that really what it's all about these days? Iv'e been wondering what the people 
who have been on both sides might say.
