personal experience, own a TM3, I rarely if ever need to use the screen. Not even for navigation. Some simple actions are almost automatic for me when I do want to toggle, muscle memory even works then. with regards to touch screens vs physical buttons, I tell friends at work who have mocked the TM3 display. put a sticker on every button then remove them as you use them on a drive. plus some cars put buttons in far worse places but as with most cars you adapt real quick. after all its not that you need more than a few buttons from the dash
