I tend to agree with you (even though I can barely read your comment :)). I haven't used Windows for years and I'd rather not to if given the choice. However, I find it very respectable to be comfortable with different platform and to be able to use the best tools on each of them. It also shows open-mindness not to be stuck into religion wars.

It reminds me of a colleague of mine who was an OS researcher. He was hacking the linux kernel all day long but still wrote his PhD dissertation using Words (when everybody else in the community was using Latex).
