I'm someone who can't survive with only one monitor. Meaning I have a large external connected through Thunderbolt and another good sized HD monitor through USB. This takes up a lot of space and its likely when I go to Uni I will only have room for my two big monitors on my desk. What will likely happen is I will use my monitor shelf to have my two monitors, speakers etc and have my MacBook underneath closed. I know on the old MacBook Whites they could overheat when using something like Insomniac but I don't know about the new MacBook Pros. I've seen a few MacBook stands designed to hold it closed and take up minimum space. Essentially, will my MacBook be able to provide adequate cooling to provide no drop in performance if I use it closed?
