exactamundo. iTunes is free. All other iLife programs are bundled for $80. If you don't buy the yearly update, you will be stuck in older versions. Much like other software.
Ok that makes sense. Now what what happen to iTunes 7.0.2 if I loaded on iLife '05? Would it get replaced by iTunes 4.7 or would my whole operating system get confused and have a melt down?
what Mac do you have Macdrive ? all Mac's now come with iLife bundled on
The Apple Installer for iLife checks your Receipts folder to see what is installed already. It also checks your application folder to make sure you aren't lying, i.e. you copied someone elses receipt for iLife to get the update which is a full app installed for free. Since it will see iTunes already has a greater major/minor value it won't change it.
