Help! I am about to purchase my first notebook computer and need some input. I do not play games but use office applications, surf the net, and like to watch DVD movies. It just so happens I am a staff member at a large university that does offer either Dell or Apple with complete customer service right here at work. Ok, everyone tells me that I need at least 512 megs of Ram and a multi drive so I can burn CD/DVD's. Between Dell and Apple which unit and configeration would you buy?
