Hello, I've just started using my late 2013 rMBP (in closed clamshell mode) with my ASUS VG248QE 24" monitor. Does anyone else use their macbook's as a desktop regularly and have not experienced any issues in the long run? Also, I was wondering if there are any disadvantages in doing this? Would it have any negative effects towards the battery or cpu/gpu/fans in the future? Btw, I keep the power cord plugged in while I have it connected to the external display too, I don't really notice the machine getting warm after 1-2 hours of usage.
