Why the chin bar? The could have easily removed it now that there is no logo on it, and the logic board footprint is now next to nothing. Their design decisions are just plain weird. Also, why is there no black version? No network ports? No USB type A ports? Really?
Logic board and speakers have to go somewhere, they can either go behind the display and make things thicker or they can go in the chin bar area.
I was surprised they did that too - I expected a look that was more like the pro display. Other than that though I'm pretty impressed with the design, and it is quite thin. It looks like how I'd imagine a 'future' computer to look.
