We need rubber grips

A little tidbit of advice to makers of readers/tablets: these things are difficult to hold because one is always likely to trigger some button or other. A good thing would be to make the buttons more distinct, harder to trigger by accident. Another good thing would be to make rubberized grip areas on the sides and the back. This would give you areas where you know you can hold without hitting buttons, and also it would give a much more secure grip. It would heighten the user-experience considerably.
