> Perfectly usable without ugly case.

Why would you buy an ugly case and not a clean and well designed, functional one ?

If you liked the original iPhone design, getting a rounded and hand fitting case would be the go too IMHO (on the size difference, there's no way out at this point)

My previous phone was the iphone 8. It’s trully a world of difference in usability compared to the iPhone 13 I’m using now. I have big hands, so I can ise the latter one-handed, but a lot of people I’ve seen don’t.
