A touchscreen is an ergonomical nightmare when vertical. I mean when you sit in front of it at a distance of ~40 cm
A touchscreen is okay when horizonzal I mean when you hold the screen in your hands (smartphone, tablet) But not for computer use.

The touch screen is fundamentally meant to be a dashboard of sorts, presenting a small number of graphics elements resembling dials or buttons. Trying to find a middle ground may lead to hybrids, which are neither good text processors nor comfortable instrument dashboards.
