Hi Everyone, I've been trying to decide how to spend the last $150 of my tax refund, but Apple seems to have solved that problem for me. I've been interested in Aperture (EDU) for a while now, but $249 was just cost-prohibitive for me. I can stomach $149, but I don't want to spend that kind of money and just be disappointed. I have a 15" PowerBook G4 (1.5GHz G4, 1.5GB RAM, 80GB 4200RPM HDD) and iPhoto '06 is constantly sluggish. Will Aperture outperform iPhoto on my hardware? I've read a few reviews from people using Aperture on a PowerBook, but does anyone here have any personal experience to share? Thanks.
