I must say, Apple is back to form. It's the first non-Jobs presentation that seems to push Apple forward - all the other ones felt incremental. This is big. I support 100% breaking out an operating system for iPad in iPadOS, it was ridiculous to try to ram a small phone screen along the 12.9" iPad.
As to the hardware - after years of nothing on the MacPro, to the point where folks started doubting if Apple was even interested in the pro market, here at least is a release with enough power and features to pretty much shut up any critics of "underpowered, look what windows and the PC world has" - even the price is super competitive for what it delivers (well, except that ridiculous $1K for the stand - what??). Sure the price is high, but if you're a pro it really isn't - if you want to play around with pro equipment, then yeah, dropping $10K-30K on a system might be a splash of cold water. But for pros, I think there should be no complaints at this point.
