As an Arch user, I have always wondered why there weren't any easy to use rolling release distros. For businesses that means never having to schedule down time for upgrading or reinstalling while still having the latest software, and I know it will mean less stress for many consumers also.

I've never tried UNE myself, but I've heard bad things about Unity. Apparently that wasn't a problem for him.

If Google got it they could integrate it with iGoogle and Android. That could be nice.
