I'd say RHEL 5 is fairly outdated and that Windows is irrelevant for a non negligible portion of development shops as a development platform and as a deployment platform.

I don't agree with that it would run "virtually anywhere" but it should at least run on every platform that has binary compatibility with the platform that a container was built for? Getting docker to work on Windows might take a while but Mac could work.

I actually do think Docker or at least the container model will change a lot, i'm considering staying with Linux as my development platform instead of Mac and that's a thought i'd have laughed at two years ago and the sole reason is Docker.
