What Microsoft Forgot to Mention About Vista

So, just as New Years came and left, so will Windows Vista upon the release of Windows 7 later this year and the upcomming beta release tomorrow. Nothing could make the upgrade a little easier for users to deal with than the knowledge that Microsoft (along with many major computer manufacturers) kinda cheated a little bit when they sold Vista.
After reading an article on Lifehacker about Windows 7's hardware requirements I found an interesting piece of information on Microsoft.com:

While all editions of Windows Vista can support multiple core CPUs, only Windows Vista Business, Ultimate, and Enterprise can support dual processors.

Although this will not affect the majority of Windows Users, I found it interesting and thought I'd share it.
