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.
