All my laptop and desktop screens are touch screens, and the laptops have pens. It's not awkward or tiring if you have it set up well. Lifting my hand from the keyboard up to the desktop touch screen to tap something is often quicker than moving there with a mouse.

What kind of screens do you use for desktop?

Either all-in-ones by HP, or Dell external touch screen monitors. There are other options available, but I've ended up with multiple of each of these, as they're available and work well IME.
