Well, the "desktop" in RT is completely different than the desktop in x86. What I said was that Metro and Windows 8 should be separate products until the x86 desktop can be emulated as an app inside of Metro.

As it stands now, your RT "desktop" apps will not run in the x86 desktop and vice versa. Those two desktops are only similar in look and feel. I do think that the Metro apps will run on both x86 and RT, not too sure about this though.

This is so fucking confusing. We have two versions of Windows 8: x86 and RT, both with two separate environments: desktop and metro. If an app can run on metro in both rt and x86, the consumer is faced with a 1/3 chance that a given app will work on their Windows 8 machine.
