A friend of mine mentioned that they thought an adapter had come out that would allow for both an external display and gigabit ethernet to be plugged in to a single Thunderbolt port. I have done some searching, but I cannot seem to find anything of the sort. Does such a thing exist? Also: 1. No, the 27" Apple Display is not an option (too expensive). 2. No, the USB Ethernet adapter is not an option (not gigabit).
