ok, i assume that when i get my mac, a snow leopard drop in disc will be inside. 1. As soon as i finish the setup, and am presented with the desktop, i will immediately put in the snow leopard disc. in this scenario, is it ok to just do a normal upgrade since the system is pretty much untouched? 2. My understanding is that if i do a clean install, i will lose iLife, and will have to reinstall it using the discs that came with my machine, is this correct? 3. I'm confused about archive and install. Will all my applications (iLife, etc) be left alone? Is this sort of like a clean install, except you have a copy of your old system files? Is it ok to delete the old system files afterwards? 4. From the scenario i described in #1 which of the 3 installation methods is the best to do?
