Totally agreed, that is why *nix and Ubuntu it seems will own in cloud computing. Others that are big are debian, fedora, SUSE, Redhat, Gentoo etc. Cloud computing seems like it will be owned by free os's for the most part on default options, thus they will win. The other surprise is that there is only one free postgres AMI yet 10 or so oracle and 20+ mysql. Granted many people make their own private AMIs but at least public AMIs on Amazon EC2 are slanted that way.
