You're right that if you've maxed out the old MBP's ports, the new one supports fewer connections at once. But I still think it's a net win because: - We need to buy and manage fewer cables. - We'll no longer have the problem of having a free port, but not the right kind. - When we buy a device, we don't have to decide which ports it should plug into. Like, when I buy a monitor, I don't have to decide whether it should have DisplayPort, HDMI, both or either.
