I do a lot of navigation and reading via keyboard, and being able to drift my right hand over and press pgup, pgdown, home, end to navigate documents is much more convenient than trying to contort my already-achy left pinky to find the fn key (and maybe miss it for ctrl or super), or worse, having to move my left hand away from home to press fn with my index finger. In general I think a lot of programmers including myself map their keyboards in unique and complicated ways. There's no reason to have fewer keys when you can have more, especially considering how others like the Lenovo Yoga have managed to fit more keys in the same space and still maintain the island layout.
