This is really what it's about. At this point it's awkward for the people who are used to every screen they have reacting to touch for MacBooks to be the only ones that don't, so Apple felt like they had to add it.

That was my thought, too. If I ever get one myself, I’m likely to forget about the touch feature and just keep using the trackpad and keyboard.

But whenever my adult daughter shows my six-year-old grandson something on her Macbook, he immediately tries touching the screen and is confused when it doesn’t respond. He doesn’t have any devices of his own yet, so his defaulting to touch is the result of very occasionally being allowed to use an adult’s smartphone or tablet.
