It doesn’t move the needle for me to purchase it. My m1 iPad Pro still does everything I want it to and I don’t use it that often, but when I do I love it.
The only thing I miss is the ability to read under the bright sun. New Tandem screen unlikely to change it, so I'm opting in for 13.3" e-paper tablet. As I often read academic papers, that should be a killer one, but new 13" iPads also look promising for that!
Frustratingly, I can't find a weight spec for the magic keyboards, so I have no idea whether it's significantly lighter or what.
Apple is pushing more for triple-A games being ported to the iPad (like Assassin's Creed they demoed), but it's a chicken-and-egg problem monetizationwise.
