I have two work thinkpqds, one has a touchscreen. I use it fairly often but, and here is what people miss out, in addition to the mouse/trackpad, not as a replacement for them.
Well with a typo suspect using touch screen keyboard /s lol.
Joking aside how often, what percent do you select or manipulate on screen vi touch vs mouse? Let’s add moving by drag and drop? Let’s now think of contextual menu. Notice these questions are in specific order as I’m sure many will know how much more of a failure using a touch screen for an OS never fully designed from the ground up for touch and instead is an after thought shows the lack of user experience or ease of use.
