I hear what you're saying.  I don't know too many shops that have virgin machines.  Most would be installing over at least a 7.x product.  I ran into some problems with NAV when trying to upgrade from LANDesk 5.03 but then that was a big jump to 7.5x.  Now in testing I'm just trying to go from 7.61 which is only one version away.

I too will probably wait for at least a .1 release.
