I need a quiet laptop. I tried a MBA. Fans like a Hoover Vac. Returned it. I understand conversely that the new Penryn MBP's are very quiet. Does that hold true when running XP in Bootcamp? I'm not sure if the power drivers work as well in Windows on a MBP as the native OS X drivers do. Is Bootcamp Windows XP on a MBP quiet? Anyone care to post fan speeds from iStat? PS Don't waste time on the "why would you want to run XP replies"; it's mostly for gaming.
