I had both iLife 05 and iWork 05, and I upgraded both, to then find 7 gb's of my hard drive were used for the upgrades. Turns out iWork didn't upgrade, it installed a new iWork right next to my old one, so I uninstalled the old one, but that was only 2 gb's back. So anyways, I was disappointed that the iLife upgrade still took up like 5 gb's. I ended up using appzapper to get rid of Garage Band and iMovie and iDvd and iWeb to get some of that space back. I really just wanted the new iPhoto, which is now driving me nuts because it imports all my Canon camera pics in at 72 dpi, when the old iPhotos used to import them at 180 dpi. I can't find anywhere to change this. And no, it's not my camera- it always stays set on Large for the picture quality, and they used to import at 180 dpi at about 8" x 11", and now they come in at 72 dpi at 22" x my god 28"!
