Why all of this and not once did you give an example of data input on the touch screen of your laptop. Not once.
You first try to deride the topic by talking about an iPad - this is not a laptop by your words you chose laptop. Why are you trying to compare or being in an iPad to this debate - it doesn’t hold water here. Yes I’ve owned 2 iPads prior.
Why would you confuse touch interaction with your iPad with your MacBook Pro?! Two different devices targeted for 2 different use purposes and the OS & UI is designed for each specifically. Again your 2nd paragraph states nothing about data input.
Your third paragraph incorrectly assumes I mentioned anything about not using a touchscreen cause one has a trackpad or mouse. I never stated such. I did state it’s much easier and much more efficient using a keyboard (for data input) and a mouse/trackpad for UI manipulation/interaction.
I think many people here think touch screens for a full computing device is better at all things than a keyboard. I’ve seen some very fast iPad 11” Pro typing by Apple employees it’s a great show.
BUT:
For short data entry it looks fast. Over a prolongues data entry, say for a full document page (8.5 x 11”) - it’s proven time and time again accuracy drops tendon strain increases (mostly due to holding a tablet) vs one trained to touch type. Think about it. We went from manual typewriters to digital to desktops and now laptops.
Many like the iPhone and Android with capacitive touch and I love it too. Yet for the multitude of keyboard shortcuts on a blackberry that power and efficiency was lost and completely unknown to majority of phone users. Today I feel the same thing has happened to Mac and PC users with keyboard shortcuts that save LOTS of time.
So where are the touchscreen shortcuts on smartphones and tablets that really make data input and object manipulation faster, powerful and very efficient? There are VERY few tasks - when you think about it, it’s not very surprising.
Again my debate is where is your use cases for real world data input - by your own words - that you do in the touchscreen of your laptop!?
Not your smartphones or your iPads or other didgital tablets. Try not to bring in other devices to falsely challenge that when neither is relevant to the device you’ve originally volunteered for this debate and consideration

great Jiu-jitsu of tech I’ll agree.
