A lot of people here who are against a mouse or cursor support just can’t seem to comprehend that this method of input does not—or will not replace ‘touch’, as ‘touch’ will always be the primary method. iOS was designed this way. However macOS wasn’t designed for ’touch’ either, yet iPad apps work just fine on macOS, they work great with a cursor too.
People who can not comprehend that, can't also realize the efficiency and practically of it. Using ‘touch’ when the iPad is flat (or slightly angled) on a surface; resting the iPad on your stomach; resting the iPad above your arm; or any scenario where your hands are parallel with the touchscreen is the best scenario to use ‘touch’. You are never going to need to use a mouse/cursor in this position at all.
The only scenario where a mouse/cursor is needed is when the iPad is docked on the keyboard folio where touching the display is obscured with the angle. You can’t intuitively use ’touch’ this way. You’ll have trouble interacting with the lower half of the display because it can’t register the tip of your finger or your nail gets in the way. Precision isn’t so great either, formatting your essay wouldn’t be intuitive at all.
Anyway, the reason most of you don’t want to see Apple implement a mouse/cursor support is because you want to arbitrarily distinguish a tablet and a computer. Which is a ridiculous mindset in itself — for us to hit roadblocks and inconvenience ourselves just to set rules on what input a device can have... when the fact of the matter is, a Mac and iPad differs by operating system and their primary input (that was designed for it). That doesn’t mean it isn’t possible for these devices to have a secondary input. Actually, the iPad already has, if we exclude the keyboard, the Apple Pencil is another input. And just like the keyboard folio and Apple Pencil, these are OPTIONAL, none of these are meant to replace your software keyboard, finger, and touch. Having an OPTION wouldn’t affect you at all. If you wanna live inefficiently because you want to differ a computer and tablet, by all means, don’t use it. You don’t have to. Nobody is forcing you to.
For people who are against touchscreens on Macs because the UI is too small and using touch isn’t as practical as using a mouse, the same can be said with using an iPad with a keyboard. When the iPad is positioned like that, it is no different than a laptop. But this is where the iPad is gimped, using ‘touch’ while docked is no where near efficient and intuitive as a laptop with a trackpad. A (MacBook) laptop is the exact same setup as an iPad (tablet) when on a keyboard folio.
The reason the MacBook is superior than the ‘iPad on a keyboard folio’ is because our hands are already resting, they’re always resting somewhere, and they’re likely resting on the palm rest near the keyboard. So reaching over to the trackpad is a far more better experience since the trackpad and keyboard are right beside each other, which requires very little effort/movement.
Compare that to the ‘iPad on a keyboard folio’: You must raise your arm and reach out to the display while trying to avoid hitting the display with your nails to have touch be registered. Your arms will be extended for a long period of time too if you are browsing a feed, editing an essay, adjusting a layout, dragging-and-dropping, composing and editing an image/video, etc.
With a MacBook, you can accomplish all this with comfort by resting your hands on a surface. Keep in mind when your arm is lifted, you are less precise too, meanwhile on the Mac, your hands are stationary which gives you more precision than having your hands wander off while they’re raised.
Another superior way the MacBook exceeds an ‘iPad on a keyboard folio’ is the range of movement. The trackpad is small, yet the cursor can reach end-to-end of a 15” display just by accelerating your finger. Your hands hardly move at all, meanwhile your arms don’t move at all!
Now with an iPad with a keyboard folio, you’ll be doing a ridiculous amount of gestures. You have to raise your arm, reach your hand on the right-hand of the display then physically drag your hand in a wide-range motion to the other end of the display. A one-time task is no big deal, but when you’re trying to be productive or having to repeat the same task over and over again? NO, a cursor is superior, and is needed when the IPAD IS ON A KEYBOARD FOLIO, not when the device is used on its own, it’s not meant to replace touch either.
Phil Schiller was even quoted that using ‘touch’ on a big iMac display is crazy because your arms will always be up, that’s the same idea with the iPad, 13” is still crazy. Having your arms up regardless is never a good user experience. I don’t enjoy browsing Reddit when I have to scroll the feed by raising my arm, while my other arm is typing on the keyboard in Notes. Drag-and-drop on iPad while on the keyboard folio is awful, both arms need to be extended and used, then you need to move your arms to one end. That isn’t as efficient as a trackpad which requires little movement. You can also not interact with external monitors too.
