I appreciate everyone posting information about their "freezing" problems. I finally decided to jump in and contribute. My problem seems totally unrelated to what most people experience. I do get freezing, but only when my wife has Appleworks open (Rosetta, PowerPC app). Then I can make it freeze in Time Machine, every single time. If I don't have a rosetta app open, it has NEVER frozen. Had it 3 weeks now, and have tried to push the GPU to make it freeze -- no problems. Very pleased with the machine, but my problem seems to be software related.
