Touchscreen is a requirement for any display for me now. I use it on my desktop and notebook daily. I have 2 24s on my desk now, one is touchscreen, and they are going to get replaced with 2 27 in or 2 32 inch Alogic or Kuycon displays when we get in our new house and got our office setup.
I don't get all the moaning about fingerprints either. I have a cloth to wipe down the display. The same people also have ipads, phones tablets etc and touch them constantly without complaints.
I think that a lot of Mac users don't understand the attraction of touch screens and I'm in that camp.
Fingerprints aren't really an issue at 400 nits or higher. Not even sure they're a problem at 300 nits but I don't have any screens that low.
I keep a microfiber cloth near me for laptops to clean the trackpad and keys and I can clean the screen too.
My Yoga has a touch screen but I don't use it. I bought the Yoga for the ports - for some reason, the touch screen model has a better selection of ports than the Yoga Slim.
