Okay, so I've read tons of threads here and at the Apple forum about the problems regarding the unusually sensitive/loud fan (and core shutdown) in the MBA. I am wondering if we can isolate the problems to specific programs/activities and determine whether these are acceptable compromises for having a thin and light notebook or to demand a fix from Apple. Having had PB 3400, PB 2400, PBG4 15" and 12", the loud fan is driving me crazy and I will likely switch to a MBP if this continues. So for me the fan comes on (at 6200 rpm) when 1) I am connected to 20" ACD doing basic chores (email, Safari, iWork, etc.), 2). When using MBA by itself just watching Flash video, and 3). When Time Machine is doing backup to Time Capsule. All these I consider simple tasks that should not slow down the machine or make it non-responsive. What are people's thoughts on this? Accept its design flaw and live with it, or would you consider switching to a different machine?
