I plugged in a new external 1080p monitor and thought at first there was something wrong with it, but no it's just the difference in crispness. Not only that you can run 2 external 5K monitors! from a laptop!
The SSD's are so fast, it's also so quiet - you never hear the fan. The only negative is it gets warm when charging on my lap.
I too don't see the point of the touchbar though, it's a cute gadget to play with. The sound is remarkable, though the whole laptop vibrates when the sound is turned up (edit: though there's no audible distortion or vibration noises which is pretty unique for a laptop too).
It is without a doubt the most perfect laptop I have ever owned, like everyone I would have liked to pay less for it. I'll use it for the next three years then give it too my daughter and she'll use it for another three years like my last one. I'm very happy with my purchase.
