I would like to inquire why the Acer Chromebook 315 [CB315-2HT] is marked as N/A for touchscreen. (It has a touchscreen.) As well, I believe that the Dell Chromebook 11 3120 doesn’t have one (but I may be wrong). Also, the same for the Dell Chromebook 3100 and 3110 (both not the 2-in-1 variants), I believe they don’t have touchscreen. (I have used both for a while and unlike their 2-in-1 variants, they don’t come with touchscreen) So I hope these can be rectified if I’m right!
