This is actually a brilliant idea. I should try this on an empty weekend or something.

A rebuttal:

1. The launcher auto-hides when you have windows maximized or over the launcher.
2. I find it so much easier to find things in the unity dashboard as opposed to menus.
3. The global menu is more consistant, but it's probably the thing that took the most getting used to.

Overall?  I like Natty.  It's gotten more stable since I installed the beta several weeks ago.

I'll be doing a longer write-up about other features and whatnot over the next couple of days, but I wanted to share this video and my thoughts with everyone.
