I recently acquired an 17" iMac G5, 1.6 PPC with 2 GB RAM. I upgraded to Leopard 10.5.8, installed iWork and iLife '08, Aperture 2 and a video game. I also added some enhancements, Divx and an I.M. program. Can anybody recommend some software that may be fun to add? I recently switched from PC to Mac. Thanks!
