I get what you're saying, but I use those keys to navigate so often that constantly contorting my pinky to reach fn is going to wreck my wrist. With the keys on their own row I can drift my right hand over and comfortably scroll through long documents with one hand, and without having to constantly be aiming for and possibly missing a modifier key. (And possibly fat-fingering the arrow keys because they're so tiny on this model.)
Plus, some people (me) are comfortable with their keyboard layout and shortcuts and don't want to be forced to change their typing habits for no significant gain, when the alternative (full row) is entirely possible and in fact present in similarly-sized laptops like the Yoga.
I ask myself, "Why would Dell change their keyboard like that, given literally all their other laptop models are otherwise?" and the only answer I can think of is, "To look more like Apple." That's not a great reason.
