I have a 1.5 Ghz G4 Mini with 512 RAM (A gig piece is on its way), and I'm really wanting to upgrade from iLife '05. Of particular interest to me are the new versions of Garageband and iPhoto. I realize that iMovie '08 won't run on my computer, but being able to download HD 6 is still a big improvement. I know my mac meets the requirements for the other software, but I wonder if anyone here has tried running the suite on hardware similar to mine. I would love to get the new upgrades, but if it runs slower than dirt, I may have to reconsider. If any of you have had experience with this, please let me know!
