I'm buying the 21.5" iMac tomorrow but I've just seen what's going on at WWDC next week and was wondering if I should hold off in case that Lion is going to be released then? I don't want to buy a brand new computer for the OS to be out of date only a few days (or even weeks) later. I remember that when I bought my first Mac just before the launch of 10.4 (Tiger?) they gave me an upgrade disc to Tiger with it and I'm pretty sure that people who bought it just before the release got sent the disc afterwards. Is this still the case?
