For the next iteration of Apple's OS I believe we should ditch the cumbersome name "Mac OS X" and not follow it with "Mac OS XI" or "Mac OS 11". We should simply call it: Mac 11. It's succinct, to the point, and, most importantly, numinous. Mac 11. The world's best operating system just grew up. Etc. Alternatively, we could christen a new name and go from there.
