With Leopard right around the corner, I've seen a number of "what do I need to do to erase and install" threads. I guess this is another one. I thought maybe someone (or someones) who's been through this experience before could set out a checklist of things that need to be backed up, things that need to be on hand, etc. in order to have a successful erase and install. Basically I'm wondering what does everyone suggest to back up (applications, home folder, etc.?)? What discs do we need (Leopard Install discs, computer restore discs?)? How is everyone planning on doing this? On a side note, I was personally wondering if when you do an erase and install, you need the original OS X install discs that came with your Mac.
