This is the price of progress, people. Would I like a MacBook that is as thin as possible and weighs two pounds but is as powerful as a MacBook Pro? Of course. And we’ll get that in a few years. But it takes time. So we can either wait, or accept certain trade-offs now. Sadly, you still cannot have your cake and eat it too.
I wanted to write a few words about the new MacBook, but this article of M.G. Siegler just captures exactly how I feel about it, so I'm going to build upon his thoughts. I've talked with some people that were expecting this machine, but now are disappointed because "I can't plug it to a display," "I have to buy an adapter"... You know, the usual suspects. The thing is, if you work in a workstation with an external display, maybe this computer is not for you.
In order to push the boundaries of what's possible you have to make compromises. It's what engineering and design is all about, compromises. If you want to design the thinnest computer, you'll need to make sacrifices in other areas in order to shine where you want it the most. This is a mobility first computer, it is meant to use on the go, without a power cord attached. That's why MagSafe was not prioritized, because it's not meant to do that. Compromises.
So this computer is marketed towards a niche public that fits within their design priorities. This segment will benefit greatly because it is the best in class in the areas where they expect the machine to excel. But if this is not your case, if you use your computer on the same desk 80% of the time, you will be better off buying a MacBook Air. Compromises were made in other areas in a way that you'll get more benefits, despite not having the "ultimate" machine.
Three years from now you will be able to buy a MacBook this thin that matches your expectations in other areas, but only because some years ago a MacBook with one port leaded the way. That's how it works.
