one more note regarding protecting my battered Pro 1x:
I ordered one of these cases, took out the wallet insert quite easily, increased the cut out at the bottom for the charging access, and figured out that if I open my Pro 1x, I can insert the bottom, keyboard portion into the case quite snugly, and then i can slide the phone close and open securely. I just have to memorize the locations of the up, down and power buttons as they don't correspond exactly, but not difficult.
Now I don't feel like i'm risking another disaster. Hope this can be of help to others.
