Whoops - connected to a tbd...or to your TBD. couldn't pick one, so i went with wrong. TAKE luck. At work i've always kept my laptop open when connected to an external display. primarily because this gives me 2 monitors, but also because they tend to get VERY hot when running closed. Is that the case w/ the MBAs? I was thinking about getting one of those arcbook things and just using a wireless keyboard/trackpad - but if the unit gets too hot to use like that, i'll just use the laptop itself. thoughts?
