Another Air question! For people using new MBA with external monitor... Do you have problems with overheating and fan noise when doing fairly sedate things, i.e not gaming? My MBA 13 will be base model with 8gb ram, with dell ultra sharp 2412, mostly for writing, some photography and e-book development, some music with iTunes, GarageBand. Most safari, mail etc on my iPad, my music and photo libraries on my iMac and time machine backup.. So won't have so many apps open at once on MBA, when at desk with external monitor. I've read many conflicting reports here about the demands of external monitor on MBA, so thought I'd ask directly outlining my intended use.
