I am sorry if this question has been asked before but does anyone know what the cost of Leopard will be? And if I have a regular Macbook 2ghz intel, if it will run it ok? I am actually a Mac convert, I have been using Windows since 3.1b. I had no idea what I was missing. I love OSX. I was going to switch no matter what, I'd rather die, then have to deal with Vista... Thanks!
