What WP do you have? My Samsung Focus soft touch button is so sensitive that I hit those buttons by accident ALL THE TIME. That's just frustrating. I'd rather not having any button at all or replace those with press-down real buttons.

Having fewer buttons seem to make interface cleaner and less chance to screw up for users. But again it's a hardware issue for debate rather than software.

Oh, I hate capacitive buttons too as do all right-thinking people, but I still vastly prefer the capacitive back button (on my Dell Venue Pro - not recommended, btw) over none at all. I don't really hit the buttons by accident myself, but this does seem to be a problem for new users (as I've discovered on the occasions where I lent my phone to someone who needed to make a call).
