I'm considering purchasing a new PowerBook... either the 1.5GHz 15" or 17". Right now I do okay with my 500MHz G3 Pismo and publish articles online with it every day, and even do a small bit of photo editing with it in Photoshop despite only having 256MB RAM. I just bought a video camera and played around with iMovie, and the speed of processing transitions and effects is pretty slow. So, I went to the local CompUSA and tried out iMovie on a 1.33GHZ PowerBook.... and honestly it didn't seem all that much faster. What gives? I would have thought it would be at least twice as fast as my machine. Does iMovie depend a lot on hard drive speed? I also tried it on a Dual 1.8GHz G5 and it was speedier, but still required a lot of sitting around and waiting. Are my expectations too high? Or is my test with iMovie just not a good indicator of how much faster the new PowerBook would be? I need a reason to justify spending $2500 for a new laptop... the superdrive is nice, but I could just get an eMac for $999 to have that feature.
