Why should that make you nervous? Shouldn't your firsthand experiences have a greater influence on how you feel?
I've never had any ill experiences with any of the Apple products that I've bought (at least not until a few years into ownership) and although I'm not interested in these new iPad Pros at all, but if I were, I'd have no worries.
Because the thing was so expensive and I’m unsure if AppleCare would cover it if it bent. I’m SO OCD that would be really hard for me to continue with one that is bent. But I see where you are coming from. They obviously didn’t bend themselves. The real question is for those that are bend, how much pressure really caused it? Was it pressure beyond normal use? I don’t know.
