So when you look at, touch, smell, and/or listen to an object, it doesn't stir any feeling in you? You don't get a "feeling about that object," purely based on its physical characteristics? I don't think you're being fully honest here if you want to make that claim.
Maybe you're just so used to things that you don't notice how they make you feel. But consider what you might feel on encountering a completely novel object - something you've never seen before. What are your first impressions going to be? Is it soft and fuzzy, or hard with sharp edges? What color is it? Does it make you wonder what it does, what it's for? Is it appealing to you, does it make you want to touch it? To possess it?
Do you like nice things? What makes a thing "nice?" Are there commonalities in what people consider nice, good, desirable? Or is personal taste just a completely random thing, with no statistically significant trends across populations?
I think either you or I are misunderstanding something. Look at the iPhone drawing again. The radius it illustrates is at the corner of the phone. It joins the sides, but otherwise has nothing to do with them. The sides could be flat or curved (as they are), and it would make no difference to the curve of the corner radius.
