Topic says it all: if, say, I bought a mac a month (or a week or a day) before Leopard came out, does Apple offer a free retroactive upgrade? (and I know that you can return it to the store w/in 10 days...but that's useless for me!) That is the one sort of sketchy thing about buying Apple products. MS offered the arrival date for Vista months in advance, and made it clear that any computer bought within that time frame would receive a free upgrade. I think that business tactic makes buyers (ie, me!) feel a lot more comfortable about dropping the cash now vs. waiting.
