a question for you programmers around... can apple speed up iPhoto so that it's zippy w/o needing a G5 or other high-end system? On my Ti DVI 667 it's pretty sluggish. I've heard the tip that removing drop shadows can speed it up somewhat, but I'm curious what it would take for the app to be sped up at the code level. or is the sluggishness just a function of dealing with hundreds of images? as you might tell i'm not very programming-savvy. thanks.
