Different people like interacting with computers in different ways, unfortunately, this one size fits all philosophy that permeates the tech sector creates a lot of tension because those ways of interacting are not necessarily compatible with each other.
A touchscreen doesn't detract if you don't use it though. I use my laptop's touchscreen/stylus pretty much exclusively for Japanese writing practice, the rest of the time it's just a regular laptop, but I'd be very sad to not have that feature when I need it.
If not for that I would 100% agree it is a nice to have.
in a perfect world. in the real world it's an added cost-to-repair, another driver stack to worry about, and a loss of nits/lumens for no good reason.
