I have a stand(another xmas gift) that will prop my MacBook pro physically on it's side, so that the machine is ClamShelled(Lid closed, but all the electrics running via a USB Hub and an external device),
Does anyone have any long term problems to report from either keeping clamshelled and sideways or with playing dvd's while the MacBook Pro is in a vertical position?
