Hi!! I'm going nuts, I am a brand new Mac person who just purchased an 12 inch 800mhz ibook that hasnt even arrived yet ( I thought that was the highest processor!) But I found out today that there are 1.2 ghz ibooks. Are there any obvious and crippling differences between the two besides speed? Would i be better to resell the 800 and purchase a 1.2 ghz? Please Help!!!!Is it worth it to keep this one?
