ASUS ZenBook 15 UX534FTC Questions & Answers

I am looking to buy another ASUS because my S15, which I've had for a while now is so good. I'm a bit confused about the touchscreen on the 534FTC, which relies entirely upon ASUS's support, which may or may not amount to much. I also am considering the 434 but am somewhat uncertain as to what real benefit there is in having a touch screen when I am using multi desktops (x8) and multi-screens (x3) for online teaching.
