The Android thing was a bit of a tangent. I did know that it doesn't use X. The point was intended to be that Linux is becoming more and more lacking as a personal computing platform, relative to the gains elsewhere in the space. The display server is one part of that- the entire user/group permission model is another part. The part of Android that is "hacky" is using a separate user for every app. That's obviously not what the Linux/Unix guys had in mind for the user mechanism, thus it's a "hack". It's not necessarily a bad thing and it's totally hidden from the UX of your typical Android user, so it's fine. Just interesting.
