Just 1 more port and they would have had it
If they had 1xmagsafe + 1xUSBc or just 2xUSBc I think a lot of the arguing about how bad it is having 1 port would have never happened. I think this was a mistake on Apple's part not just from a practical point of view but because they took the focus away from what they have produced to what it is so obviously missing. So much of every review and the comments sections are taken up talking about the single port. When I asked people about whether they would get one they all focused on that limitation and said no. I haven't actually met a Mac user yet that has said they would buy it (and there are a lot of Mac users where I work).
Even though you can argue that it is the future, I prefer a future where I can power and USB at the same time without having to remember/buy a dongle. Even if you say it is not needed, it is an image problem and I believe will drastically reduce the sales they could have had if they included 2 ports.
