Would you use a racing wheel to manage files ? What about a keyboard for drawing program ? Wo why are you complainig that controls too small to use via touch screen are too small - AND, this is why touch screen is 'minimally' useful? bro..
you guys get this wrong all the time. The idea of touch is not to replace your precious mouse or turn mbp into a 'tablet'. There are PLENTY of obvious uses for touch on mac os that include non-precise pointer requirements. E.g. almost any scrolling, like a pdf, spreadsheet, web page. You don't need to hold your hand up to do this you just do as if you are pressing ESC but move your hand an inch further. rest it on the computer. it's not hard. fingers behind the screen, thumb on front. Easy. You can even scroll around at the same time as using the mouse pointer with your other hand. This is pretty neat. Other obviousy uses, things like maps, and even things like mixers, or controls in audio software which infamously favours skeomorphic designs lending almost ideal conditions for touch input. (think multiple channel mixers sliders) And finally Taking cues from the experience when you use an ipad as a second macos screen the areas when they can make a kind of touch bar on steriods is very interesting. It's like Nortaon commander style F button control
