I don't understand why my MacBook doesn't have a touchscreen. I'm switching to an iPad Pro tomorrow. I use Superwhisper to talk to it 90% of the time anyway.

My theory is because of the hinge, which is a common point of failure on laptops. Either you are putting extra strain on it by having someone constantly touching the screen, and some users just mash their fingers into touch screens. Or users want a fully openable screen to mimic a tablet format, and those hinges always seem to fail quicker. Every touchscreen laptop I've had eventually has had the hinge fail.

Apple is capable of solving it if they want to. They don't want to (yet at least).

There seems to be some kind of incompatibility between antiglare and oleophobic coatings that may also contribute.

Every single touch screen laptop I’ve seen has huge reflection issues, practically being mirrors. My assumption is that in order for the screen to not get nasty with fingerprints in no time, touchscreen laptops need oleophobic coating, but to add that they have to use no antiglare coating.

Personally I wouldn’t touch my screen often enough to justify having to contend with glare.

Because MacBooks have subpar displays, at least the M4 Air does. The iPad Pro is a better value.
