You’re not wrong in the sense that anything you wanna do is right...for YOU. But you are wrong that mearly holding the ipad pro will bend it(thats not true)...and i got news for you, if you drop a 10.5” ipad pro 4 feet off the ground, it’s gonna shatter too.
Look. If in your heart, you really want the 11”....GET IT. I don’t think you’ll regret it. I got one, and i friggin love this thing. Best ipad i’ve ever owned. Yes it’s expensive. Yes it’s thin. But protect it in a case like any other ipad, and you’ll be very happy. I am. I put mine in a case not cause i am scared of it bending, but more because i don’t want to crack the screen. I have cracked several regular ipad screens in the past, and always use a case on my ipads now. Its a sheet of glass. Would you put your macbook into a full backpack with the screen open? No of course not.
