Depends on the world you travel in. And I don't mean third world, first world, I mean the sort of places you have to visit. Most defense facilities will NOT have wifi, and their meeting rooms will still have projectors with VGA in only. For travelers in the world that I inhabit, all those ports are a necessity. We would even still love to have a DB9 serial port because we often connect to embedded systems with serial consoles. You and I live in different worlds, even though we both probably work on very technically involved things.
