I m not in U.S. Windows 7 will not be available here until November. Only few stores will have it initially.

Same applies to me also, But its worth experimenting

People should be so lucky that Microsoft doesnt want to harm anyone legally for the silly things they do. They made this as wide open as they possibly could for people to use, with the beta and the RC, which I am currently running and is great so far, and FREE. LEGALLY!..and activated. putting $3 a week away would allow you to purchase this by the time your RC key stops working.
