Hi Maybe i am too picky, i do not know, but one the things I value the most while buying a new computer is noise. I do have a very low tolerance for noise... my house is so quiet and calm So, to the point, i recently got myself a 17" 1GHz iMAC. The machine itself is great, and i love the screen... almost perfect for all my needs... except that it is NOT silent. Although its noise levels are nothing compared to PCs (i have one PC at work that drives me MAD!) I can still hear the low humming of the fan. I have been told that the iBooks are completely silent. Is this true? What about the 12" adn 17" powerbooks? All I want is a home machine that is SILENT, is that asking too much?
