"In the past using a pre-release version of a Microsoft OS was a one way ticket to nowhere. Sure you got a chance to test out the latest and greatest version of Windows months before it launched, but the final version typically involved doing a clean install, wiping out all your data in the process. To make matters worse, if you were buying the \u201Cupgrade edition\u201D, this sometimes also involved re-installing the older version before moving to the final release."^^<http://www.w3.org/2001/XMLSchema#string>
