I've become a Droid X convert, bought it on launch day, and have a question. I'm used to the iOS touch interface, touching a button on the screen to go back a screen or to access options and things like that. With the Droid X, while a program can and does have on screen buttons, I find myself constantly using the physical buttons for accessing menus and going back to a different screen. Are the buttons going to be able to handle constant use like that?
