I called 1-800-MYAPPLE about my Mac's eligibility for the free update. The Apple guy confirmed Lion is releasing within 2 weeks! Here's the rules: you post the date and the reason behind why you chose the date. There's no rewards, except for that feeling of intellectual superiority you get when others get proven wrong xD My guess: Thursday, 6/21. Lion is not stocked yet in the retail stores, and Mac App Store is updating apps like Evernote for compatibility with Lion.
