I know that past mac laptops (that "killer whale" powerbook G3 I had so long ago) explicitly stated that the keyboard was one of the primary cooling elements, therefore there was no bypassing the automatic sleep-on-close. Note that I didn't even know you could keep the macbook running with the lid closed. One could guess that a truly vertical stand would only be blocking one of the thin edges of the macbook, while a horizontal one would block part of a large flat surface. Namely, "to get your answer, you would not necessarily consider vertical versus horizontal, but simply look at the stands and see which one allows the most air to circulate, unblocked, around the macbook." I think that in the absence of some kind of surprising physics formula, most of us would have roughly the same answer to that question. Looks kinda strange compared to the great looking vertical stands available.If computer sleeps, you should do the steps from 2-4 again or the internal display will be on.Some people will not be comfortable to run their HDDs from this position (10-20 degrees vertical inclination).You cannot use your internal IR receiver.Better bluetooth/wifi reception because lid is not fully closed (compared to fully closed one).

It's not meant to be used that way, and under full load, this probably will lead to noise and overheating. Bookarc looks great, but closing the lid means thermal problems.
