Not really, they're all quite expensive. Any tablets costing $1000+ should not have these issues. Size does matter for some, I dont need 1 TB but I would like the increased RAM (to run multiple large apps at once). Also the resale value would be very good for that model which is something I consider.
They are definitely expensive, I agree. I think if you're getting cellular you shouldn't get a large capacity though (which is kind of the purpose of cellular) - a 11" @ 256GB is $1100, which I think suits most people - as a rule of thumb, Apple charges $50 per additional 64GB.
However for those worrying about bend issues, I'd strongly recommend the 256GB Wifi - you can get it for $800 when on sale e.g. -

I would also discourage getting the highest capacity model for resale value. This is a bad idea - memory prices decline over time, and in general you'll lose a lot less value with a mid-range model like 256GB.
Personally I haven't heard anyone reflect to me in real life about bend issues though, so it's not clear exactly how significant these bend issues are - this makes the contention that "costing $1000+ should not have these issue" a bit dubious, but if you obsess about these details (and there's nothing wrong if you do), then don't buy it.
