Hello all .. Am considering giving up the portability of the iBook for a dual G4 tower if there's any interest. iBook 700 12" Combo Drive I've maxed out the RAM: 640MB I've also bought AppleCare, which is transferable and is good until August 2005. With the new iBooks being $1300, the extra RAM-what? $100? And the AppleCare being $250, I'm guessing somewhere over a thousand and under $1500 is fair.. ?
