As others have pointed out, touch has it's uses. For most people, probably not needed and maybe more of an active annoyance anyhow.

However, my Framework 12 foldable laptop with touch is extremely handy for my purposes. I intentionally purchased it over the larger/better Framework 13 because I need a touchscreen for work and I wanted it to be foldable to sit on cramped flat surfaces more easily.

I often work as a lighting technician supporting live DJs, and despite the venue having it's own touch screens, it's absolutely clutch to be able to bring my own and either use my lighting software or remote desktop to control the venue's lighting panels. Sometimes the venue will have panels that are unfortunately positioned or simply uncomfortably far away from the DJ's mixer. The mixer displays a waveform I need to be looking at to do effective lighting. Being able to have my touchscreen laptop there so I can touch the lighting cues as needed is crucial.
