What's interesting about this MBP is how many people have jumped on the idea that you need a dongle to connect an iPhone and one of the new MBPs, despite the fact Apple and many others have sold USB-C to lightning cables for a long time.
Why do people keep repeating this, even when they are corrected?
I think its stupid, your brand new £600 phone doesn't connect to your brand new £1500+ laptop, from the same company. Google with the Pixel phones gives you a Type-C cable and a Type-A cable, however the company that still touts 'it just works' leaves you needing to buy your own adapter/cable for their 2 flagship devices to even connect together.
What compounds the issue is that if you get headphones you have to go wireless or it doesn't natively work on both devices so your either left with a dongle on the iPhone, or a dongle on the Macbook Pro.
It doesn't seem like its been properly thought out, one of the biggest gains of going all in with Apple tech is that its meant too make your life easier. I got a Pixel phone cause its actually easier for me to use with a new Macbook Pro, they share a Type-C connector, both have headphone ports.
On another note I did try out the new Laptop today, some people at work got them. Keyboard is tough, the switches feel a lot nicer, the keys are wider, the whole key moves even if your pressing an edge, however its so shallow that it ruins it all for me. If it had similar travel it would be amazing. It felt fast so excited to see how much faster the new 15", it didn't seem a huge deal thinner but it was very light, almost felt hallow compared too the rMBP 13" which feels very dense. One big worry is the 13" non touchbar was sitting at 10hours battery for light usage, I have no clue how the touchbar version will get anything close to 10 hours with less battery, higher wattage CPU, extra display, extra hardware to also power the watchOS mini for the touchbar.
