My thumb would constantly interact with the screen. The only solution would be to cup the mini in my hand, which would not be comfortable or very useful. I admit that I thought Amazon had lost their minds when they increased the width of the Fire HD by giving it a wider bevel. But now that I have one I admit it was a smart design change as my thumb never accidentally interacts with the screen like it did on the original Fire. The ipad3 also has a wide bevel which prevents my thumb from accidentally interacting with the screen.
Supposedly, Apple has written software for the mini that "knows" when you're just resting your thumb on the edge of the screen and does not register that as an interactive touch. They mentioned this in the keynote. I haven't tried it out so I don't know how it works, though.
