>Microsoft Vista was a Windows 7 beta, and was "necessary" to basically experiment on the entire Home market, to make the product stable enough for enterprise.

That claim is directly contradicted by the fact that there's Windows Vista enterprise edition[1]. Vista is also supported for a full 10 years just like 7, which would be strange for something that was supposed to be an "experiment".
