Is android linux done right?

[Skunk Worx]

Android may be the fastest growing linux distribution in history.

Now that Google has open sourced Ice Cream Sandwich, will some linux 
distribution leverage the Android "Java Desktop" just as Android 
leveraged the linux kernel?

Is the Android WM / Compositor so different from X11 that it is simply 
unpossible?

Could an ICS port to X86 use bits of the open source nouveau or radeon 
drivers and thus become a fairly decent decent desktop or laptop OS, 
maybe even to the point of accessing the various app stores?

Could this be a future version of Fedora?
