the benefit is, you can feel hardware buttons.
so when i'm in car and want to answer a call i have to look on the n900. with hardware buttons i can answer the call blind, because i can feel where the "green" button is.

Sometimes it happens to me that the phone rings and the display is to slow, sometimes i have to klick 2 or more times on the green button.

Do you understand what my "problem" is?
