We all know that Lion's announcement is imminent (WWDC) but can anyone recall what Apple's past policy has been on offering the latest OSX to recent purchasers of their hardware? I know that in the past if you purchased an Apple computer within a defined time frame prior to an announcement (or is it release?) Apple usually offer the OS upgrade at a greatly discounted price but what time frame are we talking - 10 days, 30 days? Also, can anyone recall, does it apply from date of order or date of delivery?
