First, you suggest selecting is a touch pad strength, considering the mouse is pin point accurate, surely that's even better for selecting.
Actually, what I said was, "the trackpad is great for gestures as well as movement/selecting". The point being,
gestures are a particular and unique strength of the trackpad, which also can handle cursor movement and selection. I wasn't saying the trackpad is
better than the mouse for selection. The trackpad's strength in selecting is that it's really close by - I can make rough movements of the cursor (say, selecting the current word, line, or paragraph) using my thumb
without moving the rest of my fingers off the keyboard's home row. By moving my hand perhaps two inches towards me, I gain complete access, for fine selection, two-finger scrolling, and all sorts of other actions. Move my hand two inches back up and it's on the home row again and likely lined up with the proper keys already. In contrast, with a mouse, it's at least six inches off to the right, and getting my hand back on the home row afterwards takes longer and it's more effort to get on the right keys - it's a larger context/cognitive switch (no, neither is an enormous effort - I can handle both just fine - but multiplied by thousands of uses every day it adds up). Further, the mouse might be several inches one way or the other, since it's an absolute input, while the trackpad is always in the same place. The trackpad is a relative input - I can put my finger down on it anywhere, and that matches the cursor's current location.
Don't forget your left hand is hovering over 3 more control keys plus the multi button mouse functions.
No, my left hand isn't hovering over those keys unless I first lift my hand up from the home row.
Things such as click, selected, drag, move, drop etc. Will always be so much easier with a mouse.
Decidedly no. I barely have to take my fingers off the home row to do any of those actions (and I can do them all in my normal text editor without taking my hands off the keys at all). You have to move your hand much further and get it oriented on the current position of the mouse before you get to use those extra mouse buttons, and then move it further back afterwards.
There's a store across the street from where I live. If you're standing next to me on my front porch and you have a
really fast hi-performance car (let's say it's a Tesla Roadster), I can still get inside that store before you, because while I'm heading for the store's front door, you're heading for your car, starting it up, driving there while sharing the street with other cars, and parking. Even if your car can go dozens of times faster than I can run, I'll still win (if we're going somewhere a mile away, then, sure, you'll win - by a lot). Lots of computer work involves
thousands of those very short races.
Just because it's old doesn't make it no good..
Much of my time in front of a computer is spent editing text (both code and prose) using an editor that was first written over 40 years ago (
vi, which begat
Vim, which begat
MacVim). I know the value of old technology. The mouse is relatively new, compared to the keyboard.
