Weird. I’ve tried it and seem to clash with your proclamation. Touchscreens (or “vertical touch input”?) are a much faster way to navigate the screen. Consider this: your cursor is in the upper left corner of the screen and you want it to move to the lower right corner of the screen. If I use a mouse, then I must physically move the mouse to get the cursor all the way across the screen. In most cases, I have to pick up the mouse when it reaches the limit of the area I have allotted to my mouse. With a touchscreen, I reach for the spot I want to go, touch it, and the cursor is there.
What people seem to think is that it’s all or nothing: you use all touch or all mouse or trackpad or all pen, but never a combination. The smart person uses whatever combination works. For me on my Surface Pro, I navigate with my fingers 95% of the time, and use the pen the other 5% of the time. I rarely use the trackpad. Touch and pen is much, much faster in every way for me than a clunky old mouse.
