Glad to see that I'm not the only one wrestling with this. I had decided to upgrade for the new screen. Once it became clear the 11 inch wasn't going to get it, I had to decide about going up in size to the 12.9 inch. All my iPads have been 10.5 to 11 inches.
Decided to pass on upgrading this time. But then...
I drew out the dimensions of both on a piece of paper. The 12.9 wasn't *that* much larger! I tried carrying it around. Maybe it would work! I ordered a cheap 12.9 inch case on Amazon that will be here in a couple of days. Figured it was an easy way to see how I like the larger size. Changed my mind. I decided to go ahead and order the larger 12.9.
Then I remembered going for the 7 Plus iPhone. It was the only Plus/Max I've had. I hated it. It was too big. If I wanted a larger screen, I had the iPad.
Then I considered weight. The 12.9 is about 50% heavier. When reading, even the 11" seems too heavy at times.
One more thing to think about. Just what exactly do I use the iPad for that the new marvelous screen would be an advantage? I do photo editing, but do that on a desktop with a large screen. Even the 12.9 isn't large enough for that for me. I don't stream on it. I do mostly web browsing, email, reading Apple News +, and some non action packed games. Really, the better screen would be great to look at, but it really won't be adding much value for my usage.
So, I'm back to not ordering it. Instead I'll have some coins to toss at a new 2021 Apple TV 4K and some Airtags, ya'll. And an empty 12.9 inch iPad case. 😁
