I have a dillema. My apple 1yr warranty is going to run out in a few months on my g3 800mhz iBook. It was bought in Sept. 2003. It has 640mb ram. Now I could purchase applecare but for just a little more I could just sell my current ibook and get a new g4 1ghz ibook. So in all I would maybe only take a $400 hit as opposed to like $250 for the extended warranty. I would love to upgrade too as this g3 is a little lack lustre at times when doing things in Photoshop (which is a big part of my job). So how much faster is the new g4 ibook 1ghz with 768mb of ram compared to the g3 I have. I looked all around for benchmarks but didn't really come up with anything useful comparing the two.
