Well they had a demo of Photoshop running on the iPad. That alone is enough of a pro app that it drove Macintosh sales for years.Upgraded from the generation 2 to this one (12.9 inch ) but will be my last iPad Pro unless and until Apple actually has a better iOS with apps that can take advantage of all the hardware. My previous iPad Pro 12.9 inch was all I really needed, but I liked face ID, plus the pencil charging system on the iPad itself which is why I bought it. Hope Apple is listening to us and actually gives us more in the iOS next time.
I too want to see more apps that take advantage of the hardware, and I wouldn't be surprised to see more iPad-specific features added to iOS in June at the dev conference.
