I've not used one, but it seems poorly thought out as you have to take your eyes off the screen to use it. Also, if it is useful, surely there should be a discrete keyboard that has it... I use my MBP mostly with a full sized keyboard, mouse, and additional monitors. I think I'd rather have a MBP with a conventional keyboard, and add the touchbar with a discrete keyboard if I decide I need it.
