For me, 16GB ram and missing ESC key are big limitations. I think a lot of frustration here is if your time is money (aka a professional) and you have a big budget, you are still stuck with general consumer level hardware. There aren't any other options from Apple right now, and likely not for at least another year.

I love my Apple watch, iPad, and iPhone...but those are all "best of breed" imho. I was waiting to purchase the Macbook Pro, but it's pretty mediocre by my measure.
