For what they were introducing, this is outstanding. For the the MB Air, they didn't just nail it, they knocked it out of the stadium - and it was a domed stadium!
Look, I get that if you render 3d animation for Disney while editing your 8K indie film using 100 megapixel RAW files from your 100K image library in your 256 track music studio, that 16GB is nowhere near enough memory for you. So how, exactly, did you do that on the MacBook Air last week? You didn't. This machine isn't for you (or me, but the rest of my household will love it). Double the battery life and triple the performance while removing the fan and maintaining the price point of an already successful design is just outstanding. There is nothing to fault here unless you were holding out for a Mr. Fusion powered laptop that runs on garbage - forever.
For the MB Pro, "Pro" doesn't just mean 3D animators and Video editors. Some professionals do things like spreadsheets and presentations. In fact, and this is true, MORE professionals use spreadsheets and presentations than edit video and render in 3D. A LOT more. Again, if you are a high end content creator, they didn't make this machine for you. You have complex needs, and Apple is building a foundation first. That way, when the "pro enough" machine comes out for you, you will be able to make a presentation to pitch your 8K 3D rendered Opus to the studio and include a spreadsheet that shows how it makes financial sense for them to back you. It would be a bummer if it rendered video, but couldn't do the basics, right? Let them get the platform out and improve it up to the high end.
This was a really good start. Sure, I wish there was a 16" MB Pro with Pie in the Sky performance and week long battery life. But at least have the good sense to realize that isn't a remotely realistic expectation.
