Hey all. Im goign to be getting a new iBook through the ADC Hardware Discount program but dont have much to spend. Im getting the 800mhz iBook 12.1inch screen and was wondering if 384 megs of ram is good enough. Is 640MB really all that much better than 384? I have half a gig in my PC and i dont ever go over 300, but i know UNIX likes its memory...Will I get by with 384 and have good speed?
