Yeah, I was wondering about that. Greg glossed over the hardware issue and only mentioned that "....back in August I purchased a new system and recently decided to investigate the $15 Windows 8 upgrade" without going into the details regarding the system he used for the W8 upgrade.

Bad techie.

I guess it's fair to assume that if one purchased a new system after June 2012 that the system is 64-bit. So, does the Upgrade Assistant auto-magically detect which version is required for the hardware or, (forgive me if I missed something along the way), does that mean that W8 is not available or not compatible with 32-bit systems?
