I tried Insomniax and Caffeine. They both seem to not work, when I close the lid the notebook sleeps. I am planning on buying a 40" Tv, wireless keyboard and mouse + 5 foot HDMI to mini-display port cord so I can come back to my dorm, plug into the TV and shut the lid, and basically have a desktop. Lion doesn't seem to work with these? Or the Air? Anyone tried this on Lion. I never tried to use these programs on SL.
