Sorry if this is a dumb question. I got my new macbook pro last night, my FIRST Macintosh. (woo-hoo) So now I'm going through the setup, downloading updates and am about ready to start installing programs, but I'm wondering: when I decide to upgrade to Leopard when it is released, will I need to re-install everything, or does Apple intigrate all that? You know, changing OS on a Windows PC was a HUGE ordeal: create backups, re-format harddrive, install OS, download drivers, re-install programs, re-install all back-up files.. Is it like this on a Mac? If so I'll just 'take it easy' and not install everything I don't immediatly need so I don't have to do it all over again in two months... Thanks!
