Okay, I'm doing a presentation on Mac OS and some basics surrounding the platform. I'll be presenting to beginners, so inevitably I will have to discuss price. This is where I need some help. I went to DELL and was looking at these notebooks here, can someone tell me how these stack up against for example, an iBook or PowerBook? I see for example, a P4 for $1000+ which sounds pretty good. I know it's a DELL, it's got XP and all that, but what makes the iBook or PowerBook more worth it? In other words, how would you convince someone that Apple is the better way to go (for a general purpose machine)? PLEASE do me a favor and don't turn this into a 'DELL sucks' or 'windows sucks' bash-fest. I need concrete evidence and facts to back me up. Thanks a lot in advance!
