ModNote: Please use this thread for all questions related to the differences between the $29 SL upgrade and the $169 box set, including who needs to buy which, whether the upgrade is truly an upgrade-only or will work on other Intel Macs, etc. Bear in mind that the answer to some of these questions may not be known with certainty until SL is officially available in stores. --mkrishnan Hey, With all this talk of Snow Leopard being $29 for current 10.5 users, I do wonder does this mean Apple will make an upgrade DVD ($29) and separate full version DVD ($129)? The reason I ask is because they are always careful to point out that current LEOPARD users get it for $29, they do not say it is for everyone at that price and there are plenty of people with Tiger who meet the requirements of 10.6 (my Aluminum iMac came with Tiger pre-installed and a Leopard drop-in DVD in the box). Or perhaps they will require Leopard installed in order to perform the upgrade or the user to put in a Leopard DVD to prove they own it or something? Or maybe I am just reading too much into this and it will be $29 for the full version we can install any way we please without special restrictions? I am just semi-worried because if Snow Leopard was going to be $29 for all mac users they would not specifically go out of their way to keep saying that "Leopard users would get it for that much" they would instead say it will be "$29 for current mac owners" or just "it will be $29", what do you guys think?
