Well, hold on a second, it will no longer work beyond August. And either you have pay for the final version of Windows 7 or come back to Vista.
So, what's the deal? I test it, I send feedback and I get caught. Is this a Beta testing program or a new marketing campaign.
Please Microsoft, I'm fine with beta testing, but give me a free copy after that. At the end you're just allowing 1 million of beta testers. Probably a good price for having a much better product.
