Pretty straight forward question. I currentl have a Mac Mini, and use Imacs at work, but want to buy a Mac Book or a Mac Book Pro soon. Will OSX 10.5 be a downloadable upgrade for free, or will I have to buy it? If I have to buy it, anyone know how much it may be? I don't know anything about Apple's usual OS price point. I'm thinking I might just wait for upgraded Mac Books if the OS is coming out sometime before 07. Any help would be great! Thanks!
