Okay guys, talk about a disappointment! I just picked up a new 20" Intel Core Duo iMac from the Apple Store and after transfering everything over from my old 20" iMac (still keeping all the data on my old iMac though) I ran a startup test. The Core Duo iMac clocked in at 75 seconds exactly from desktop to login screen restart. The iMac G5 clocked in at 38 seconds (!!!!!) exactly from desktop to login screen restart. What in the hell is going on here? The only thing I could think of that would be in the G5's favor is the 2GB of RAM it has over the 512MB in the Intel iMac. Would this really make that big of a difference and actually make the Intel iMac start up in its touted 18-second time if it has 2GB of RAM? This really makes me want to return my new iMac right now and go back to the G5.
