Hi, I am about to purchase a Powerbook G4. I am trying to decide between the 15" 1Ghz and the 17". I will be doing audio recording and mixing and graphic design work. Screen size, bluetooth, airport, and OS9 bootability are not issues. Size, weight, and price are minor issues. RAM speed, graphics speed, and battery life could be an issue if there was a major difference. Which will be a more reliable and useful machine? Will the aluminum construction, more solid illuminated keyboard, rubber-mounted hard drive and new (better?) design of the 17" make it better? Or does the fact that the 15" has been around a long time and hopefully been refined and the problems worked out, make it better? Are there still existing problems with the 15" 1Ghz? Do the keys still imprint on the screen? Is it still flimsy in construction? Any others? Opinions and information are greatly appreciated. What should I buy!? Andrew
