I recently bought an iPP 12.9 and also just registered here so I could share my experience. I agonised for a month over this issue, watched as many videos on YT as I could find and read dozens of reviews and articles. But first more about my setup: I have an iMac, MBpro, iPhone X, Apple Watch and needed an iPad to complete the lineup. Since I already have a laptop, I thought for portability reasons, I was leaning more towards purchasing the 10.5 iPad, especially since I could get the iPad and ASK for the price of the larger model.
Once in Apple shop, I played with both models for almost an hour, comparing them side by side, opening same applications on both, trying to make a final decision. BTW, I really disliked both ASKs - luckily, I should say, since in my view, iPad as a mobile device, should primarily be used with your hands (being a pro mdel or not). Once the ASK was out of the picture, it was easier to make a decision. The bigger really is better - it just felt right to have that large screen, use it with both hands, enjoy split screen apps and yes - that gorgeous onscreen keyboard, which I just used to write this piece. Using it is just so immersive and hands on that although typing this on my laptop would have probably been much easier, there is just that element of pure fun when I have the iPad propped up in my lap while laying on the sofa, typing away. Also, there is no heft to this model; it is still way easier to carry around than my MBP.
I bought the white model in the end (yet another issue I pondered forever), although all my previous Apple purchases ended up being space gray. White just looked better to me this time, blending in with the white background of gorgeously looking websites on this large screen. I thought the white bezels might bother me for when watching videos, but it ended up being a non issue, once the lights were off - again maybe because this screen is so much larger than on other iPads, that you eyes are really focused on the content and the bezels sort of disappear.
I guess by now you realised that I am very happy with my choice and have no regrets. Choosing the smaller model, I am sure now, would’ve been a mistake in my case. Yes, I also bought the pencil and leather Smart Cover. I recently started taking German lessons, so having the textbook open in PDF on one side (to highlight text and fill in blanks) and Notability on the other to write down lesson notes even now puts a smile on my face
