I've decided to make the switch!Presently have a Sony FX3110 Vaio laptop .Spoke to an apple rep and was advised to just buy the 20", 2.16 as configured. All I'm doing is writing that classic novel and surfing the web and delving into the creative side of the OS system. Who know about the other creative posssiblities as I explore Ilife. Other software added is Ilisten (due to wrist pain). Also purchasing the Ipod Nano 4gb.. I just want to be sure I won't need extra RAM or memory. Any advice?
