Windows can also execute all the Java and Ruby stuff that you see in nix platforms.* Really? Hit any Ruby mailing list and every second post is a Windows user complaining that something doesn't work. Not just obscure things either - DataMapper doesn't work on Windows, or didn't a few months ago. Capistrano, the "official" Rails deployment tool, is not supported on Windows. And good luck with any gem that requires compilation. Not to mention you lose out on all the command line tools. You'll need to install cygwin, of course. At that point you may as well just stop trying to run unix on a Windows box and just, you know, run Unix.
