I have a question about charging with a thunderbolt display. I just bought a new MacBook Pro with retina display and am using it frequently at home with a thunderbolt display. I have been told in the past to only charge my computer when it needs it and that it isn't good to leave it plugged into the charger all the time, but with the thunderbolt display the computer can only be closed and used with the thunderbolt display when it is plugged into power, otherwise it has to be left open if not connected to the power supply. My question is what do you guys do? Do you just leave your notebook open (a little annoying and takes up more desk space) when using with a thunderbolt display, or just go ahead and plug into power even if it doesn't need to be charged and leave it closed? Thanks!
