If I'm going to be running programs like iTunes, iChat, Safari, Pages, Acquisition, and watching DVD's would I notice a speed difference between and intel mac and a G4 mac? If so, which would be faster and by how much? Just curious if I should wait until July for the Macbooks (new AI article) or just get an iBook G4 for $800 that will do what I want just fine. And if I get the iBook I'll get a gig of ram to speed it up a bit.
