CameronWolf writes "Just in case there was any doubt about Apple computers decision to sell applications they used to give away, I got this response, via email, from Apple upon my enquiry: 'As the iLife applications have become increasingly integrated it has become more and more important for a user to have all of the "correct" versions on their Mac at once, working together, giving a unified user experience. This is one of the main reasons we've decided to offer iLife in suite form only. In addition, for iLife users who want the latest and greatest applications on their Macs, the iLife suite is priced very affordably.' Apple are running an upgrade scheme for those who bought a qualifying Mac after Jan 6th. Too bad I just had to have the iBook G4 the second it was released!"
For those who used only the free iLife apps before -- those without SuperDrives -- this reason doesn't make any sense. If the goal were really to make sure you had the latest versions, they could simply make the latest iMovie require the latest iDVD.
