It's not just the curve. It's the usability and reliability of the things. The hockey puck mouse was noticeably unusable within seconds of putting it in your hand. Pretty much the first time you tried to move it, or click, and the mouse had rotated to some indeterminate angle...it's like it went directly from the designer's drawing into production with absolutely no use-testing. The Mighty Mouse is likewise an unreliable piece of garbage, yet with no way of fixing its primary, and easily noticeable problem, the clogged ball. It's like the purpose for the entire transition from balled mice to optical mice was never a lesson Apple learned. And again, this is noticeable within a very short time-frame under use-testing. And this was a $50 piece of hardware!
