There are subtleties in graphic design that are not obvious until you have studied it. In this case making the menubar the exact height of the notch has a couple of problems.I have been wondering the same thing. If they had to make the menu bar larger to fit the size of the notch, I would have thought they would have made it exactly the same height. It appears though that the menu bar is even larger than the notch, which seems so odd to me. I honestly think that makes it even worse.
If touch were brought to Macs, it's not really likely that anyone would use touch exclusively. It would become part of a multi-modal control system along with keyboard, touchpad, and mouse. I use an iPad Pro most often in a keyboard case with a mouse. It is sitting vertically. I use a combination of touch, mouse and keyboard depending on the action and on what seems appropriate at the time. Sometimes you click with a mouse, sometimes a finger tap is more direct. Scrolling may be done by touching the screen or with the mouse scroll wheel. Keyboard shortcuts are part of the mix. If something needs to be moved on screen, touch is often the best method. Touch can be more engaging and direct but less precise; sometimes you want quick and direct, other times you want precision. We have a lot of users who are used to touching their devices to interact with them, it would not be foreign to them to touch their Macs. In fact it is frustrating when they can't.Eh, I'm not so sure. I honestly don't think Touchscreen functionality is going to work in a desktop-type computer. It works on iPhones and iPads because those devices are able to be oriented and operated parallel to the ground plane - ie, laying flat. That means that all the operative manipulation occurs with the arms and hands in what is mostly a resting state of being.
However, touchscreens oriented perpendicular to the ground plane, as a computer screen would be, means that your arm has to be held aloft by itself. Easy enough when you only have to tap the screen a few times. But try holding and moving your arm around a screen for just ten minutes. It gets tiring! No, I don't think touch capability is coming to Macs anytime soon, and even should it do so, I don't really think it'll be anything more than a gimmick - I strongly state my belief that it will be as well received as the TouchBar...ie, lukewarm at best and largely ignored by devs.
