Yeah, kind of like that (except laptops have a built-in keyboard/mouse, so it's not as much of a problem as, say, a desktop where people rely on their own existing hardware would be). I'd wager most people buy those devices because the rest of the machine is so compelling, despite the lack of ports.

Anecdotally, it seems like each HN thread about new macbooks also has plenty of comments from people complaining about the lack of ports and/or wishing for more. I don't see a lot of people saying the equivalent of, "Apple's never gonna bring those ports back, get over it and get used to it."
