Windows 7 - No upgrades from XP to Windows 7?

You won't be able to upgrade from XP to Windows 7

"A lot of people who are skipping Vista but considering Windows 7, on the theory that it will be a greatly improved product, sort of a Vista R2.
If that’s your strategy, you probably need to be aware that, at least in the current not-a-beta release, upgrades from XP to Windows 7 are blocked. (I don’t know whether this restriction will be in the final edition as well, but I bet it is.) You can do a clean install only, with all your old Windows files going to a Windows.old directory and none of your files and settings transferred (you can, however, use Windows Easy Transfer to save settings first and restore them later).
So the compatibility issues you’re ignoring right now aren’t going to go away. If you have apps or hardware drivers that only work on XP and aren’t compatible with Vista, you’re going to have those same issues with Windows 7, which isn’t going to magically fix anything."

Well, those people should really have gone to Vista. Nothing wrong with it, just some people claiming it sucks even though they haven't used it.
