I was at my local computer store, and they had 2 of those 23" HD displays hooked up to a Power Mac G4. I just stood there in awe. Pretty spectacular site, I couldn't imagine having that kind of setup. I think the 17" screen looks bigger on the PowerBook because it has a much thinner frame around the screen. Same size screen, just an optical illusion. Overall, the 17" PowerBook is a very impressive machine. I saw that 17" Toshiba? laptop at Costco, the thing is rediculous. It can't even begin to compare to the Apple.
