Reaching up to touch the screen is slower than reaching down to the trackpad. Also consider trackpoint.

Skilled users can make the reach and the motion one. You don't need to stabilize your palm on the rest to use the trackpad. Same way I don't need to use F and J for the keyboard (and kinda wish I could remove those annoying bumps)

I give you an example on this page of comments, so you can check if my informal results apply to you too.

I am moving my finger on my touchpad to move the pointer to more or less match what I am reading. I am always close to a Reply button or a vote one. There is no point reaching for the screen with my hand and touching those links. Furthermore they are way too small to be pressed with a finger. They are probably too small for a pointer too, but that's another issue.

Hoever, when I open an empty tab, type new in the URL bar and FF completes it to the URL of this site, and I press return, I usually end up with a Login link in the top right. If I reload the page (ctrl-r) I am logged in. For some reason either FF is not sending the session cookie or HN is not doing what it should on a cold session. This is also another issue (sorry) but let's say that I want to login. My pointer is far away from the login link. My fingers are not on the touchpad. Is it faster to move my right hand towards myself, touch the touchpad, slide the pointer to the link or moving that very same index finger to the link and touch it? My laptop does not have a touchscreen but when I used a tablet with a mouse and a keyboard I reached for the screen many times. Of course a mouse is less efficient than a touchpad, except for games, but I also miss the touchscreen sometimes.

And I would use if to press the reply button below this line I am typing. Let's see where the pointer ended up while I was typing... At the top right corner. Moving it to Reply and clicking is slower than touching the screen.

I do that too. I tend to "park" my cursor near where I am looking, or near where I anticipate clicking next.

Entirely depends on your relative proficiencies and preferences, I suppose.

When I had a touchscreen, I used it with a trackpad and a trackball. All three input devices had utility to me, so why not? These days I sometimes use a laser mouse rather than trackball, but same story (though my MacBook doesn't have touch now). I always prefer trackpad to scroll wheel for scrolling, for hopefully obvious reasons (range of motion and precision are both way better). I do know I got use out of the touchscreen even though I can't think of a hard rule for it. It's probably just nice to have on a case-by-case basis.

I totally agree: having several different input devices is the best scenario.

Personally I would not use the touchscreen very often, but I would use it sometimes to press buttons and maybe even to scroll. Maybe the resize handle in the bottom right corner of the text area I am writing now is a large enough target for a finger. On a laptop: raise a finger, drag and go back to the keys? Probably. With a desktop computer with a keyboard far away from the screen? Well, the mouse is also far away from the hands so who knows.

I never have a real use case for a mouse but sometimes I follow a link from HN to a game in which a mouse would be better than a touchpad: move move move click click move click is great with a mouse and terrible with touchpad of all kinds. My mouse is in a drawer somewhere.

I am a fan of touchpads with physical buttons. I think that only HP is selling them anymore, on very few ZBook models (maybe a 16 Fury?) and Lenovo still has them in laptops with their stick in the middle of the keyboard. However the Lenovo buttons are at the top of the touchpad, where the thumb rests if the index finger operates the stick. The thumb rests below the touchpad when operating the touchpad.

Thinkpad fans will tell me that those buttons are close to the space bar, were thumbs rest all the time and they are right. Their little stick is very conveniently placed but I never manager to operate it as efficiently as a touchpad, which required zero training. My old ZBook has both the stick and the touchpad and two rows of 3 buttons, and I've never learned to move the pointer with the stick, both Windows and Linux.
