There is still the confusion about whether people are referring to "upgrade" as a verb, such in upgrading an in-place install of Windows, where all your programs and settings remain the same - which is what the above page talks about - or, using "upgrade" as an adjective, such as an upgrade copy of Windows 7. The word is the same, but they mean different things.
Since even many people who can do in-place upgrades of existing installs are going to want to do clean installs anyway, the question is how does the upgrade version of Windows 7 work. Unfortunately nobody knows just yet, but most people are secretly hoping they can do the old double-install trick that you can with Vista upgrades.
The big question is whether the upgrade version of Windows 7 can easily do clean installs without too much verification of previous ownership.
