Well, it's not always either/or. For my tablet (an old Samsung Slate 7 running Win 7), the touch screen interface that comes with the Win 8s and above would be fine, maybe even superior. However, the problem with Win 8 was that it seemed dedicated for touch screen use, but most of the original adopters worked on desktop pcs using Win 7. So, the touch interface was counter-intuitive, time consuming, inconvenient, required learning how to swipe
, and had no advantages for the desktop user. End result: people still use Win 7, and a keyboard/mouse combo. Win 10 is/was supposed to solve the problem using the same strategy used by 8.1, but the hope is that it will be an improvement.
Btw, I have a bluetooth keyboard and usb mouse for my Win 7 tablet. But, the touch screen lets me do simple tasks on the subway.
