I got my 12.9" and it is brilliant. The screen is fantastic. I don't get the pearl clutching about blooming... I am not a professional photographer or graphic designer, so it may be different for them. For me it is remarkable. I will give you an example: watch Season 2, episode 1 of For All Mankind. After the recap and and intro news reel, there is a scene on the moon and then the opening credits. It looks amazing. The blacks are super blacks and the whites and colors pop. Then in the credits, it is basically white letters against mostly black. The white letters are crips and perfect. If that is blooming, then... I don't know, I don't see it. Don't believe the people who have had some axe to grind about this screen. It is brilliant. For professionals who need certain things that I don't... I can't comment on that.
The pencil works great... I have worked through many apps and videos and games. It is everything I had hoped. I have used or owned pretty much every flavor of iPad. The shadow complaint about the top of the screen. I guess I can see what people are saying, but I actually would have thought it was a purposeful tiny bit of 3-D effect if anything. Not an issue... again, unless it impacts someone's professional needs that I don't know about.
This is an amazing bit of kit!
