Hey! So I am going to buy a new rmbp 13", but I have a little problem. I can only use ethernet in the dorm. So the next step: I need an adapter that converts the ethernet cable to USB or Thunderbolt. I have 2 of both in the macbook. Which do you suggest? First, I thought It would be USB. But then I realized, if I used 1 USB slot all the time, then I would have only 1 left, and that could cause problems.(For example, I want to charge my phone, I want to connect external hdd,etc.) So then I considered Thunderbolt adapter, but still do not know. What do you suggest, or how would you solve this? Unfortunately, Wifi is not an option, don't ask me why. I have to adapt to the circumstances.
