Since we're on the subject of iLife '08, if anyone purchased a Mac after Aug. 6, 2007 - you can get a copy of the iLife '08 software for only $9.95 from Apple.
Check this link to see if your Mac qualifies (since most Macs out there as of Aug. 7th still has bundled copies of iLife '06 in the restore DVDs) http://www.apple.com/ilife/uptodate/
Yes, because iLife comes with all Macs! Those discs are different than retail copies of Mac OS X. But when a new version of iLife comes out you have to buy it.
