Not OP, but I enjoy touchscreens on laptops also. I can get by without it. I see it as a nice to have but not a necessity. It won't make or break a decision when choosing a laptop for me. Here are some reasons I like it when I do have a laptop with it:
- I think it's a better zoom experience. You can get a similar experience with a touchpad, but it's just nicer to touch the screen where you are pinch zooming IMO.
- Signing documents. I don't do this often but much prefer to use a touchscreen over a track pad when I do have to.
- Some games are better. Again not a big part of my life, but occasionally I'll play some drawing game where a touch screen shines.
- My kids understand a touch screen better. Occasionally I am on my laptop showing them something and them having the ability to reach over and touch the screen directly is a better UX for that situation.
- I do kind of like to scroll with it sometimes, but I can't really say why.
Again, not a make or break it feature for me, but all things being equal I'd choose to have it rather than not.
