For a device at that size, weight, and cost you would be better served buying a Macbook Air.
Apple has dozens of devices for dozens of use cases and types of buyers. I would never use the new MacBook (not good enough specs), and most of HN thinks it's a terrible idea. But my wife loves it. She doesn't need to run a virtual machine or plug in i/o devices or use 16GB of RAM, and it helps her do what she does better than ever.
If you look at Apple keynotes through the lens of, "Will this product change my life?" you'll likely be frequently disappointed - they're building products for a wide spectrum of users. But every now and then, they'll likely absolutely nail what you need.
If you buy a Macbook Pro when you need a laptop, it doesn't matter if the Macbook Air isn't for you. Apple still wins.
