But the bigger problem is that I like being able to use friends' mice if I find myself without one, jack HDMI into my laptop for random conference room projectors (my MBP has HDMI out, it is frequently used), etc. I can carry around adapters/dongles, but I have multiple bags, and adapters don't always come with when I'm throwing my laptop into the bag I'm using that day. So the chances that I'll have something I want to use and can't because I just don't have the adapter on me are pretty high. This is a problem I never have on my 2013 13" MBP because of the port selection, but that I will if I don't change behavior if I get this 16" MBP (which I'm seriously considering).
