I have a new Google's Pixel LS with 2 USB Type-C ports (at this point the only one in the world to have 2 as far as I know) and it's amazing. I can plug the USB Type-C charger from either side of the laptop. When was the last time you were able to do that?

This was a minor bump, I'm holding out for something bigger once Skylake is ready. Hopefully that will include USB-C.

Only if they didn't sacrifice the mag safe in favor of it like they did on the 13 inch.

The mag safe was one of the best inventions for MacBooks ever and it is sad to see how nonchalantly they retired it on the 13 inch. And I doubt the rumor it was because it is too light now. The mag safe is for when you trip over the cable with your leg. Doing that, you will always do so very abruptly. And so the weight of the MacBook cannot be that big a factor. Other wise, comparable things like the tablecloth trick would never work. The glasses and plates also do not weigh a lot. But tug on the tablecloth abruptly enough and away it goes with the glasses and everything still on the table. Same thing happens with a mag safe connector.
