I have no qualms in admitting that I am pretty much a one-OS person. Having grown up with Windows, I have struggled, tripped, crawled and somehow managed to survive in this hopelessly zesty world of research where Linux has come to become a religion...
You can just say that for a person who is so less inclined to find "discovering new commands" as a pleasure giving exercise, I have chosen the wrong profession...
But here I am... with a (primitive) 30 GB hard disk machine which can boot into 3 Operating systems namely Windows, Ubuntu and Xen, (I need all three to compare performance).... cyphering through the long list of configuration files.... and wondering if the solution to my whole research problem isn't simply for the whole world to accept one single OS that is just good enough...
How much simpler would that be...
