This is just silly. Emacs isn't an OS. It provides an API to some library and system calls, but it isn't even multi-threaded.
If your comment was meant as a hat tip to the Symbolics Genera system, that was a full-fledged OS, then there could be debate. I love Lisp and would dearly love to customize my Jelly Bean experience with it, but then we'd need to get into a discussion of what is really better, and 80's OS or Android.
