They seemingly wanted to design the entire interface around touchscreen 2-in-1s. If you went in a Microsoft store around the time windows 8 came out, they were leaning really hard into the 2-in-1s. I got a surface pro 3 at that time that I used to take handwritten notes in school, and the windows 8 interface was honestly awesome with that use case. On my desktop PC, though, I held out updating from 7 until windows 10.
