You seem to be downplaying the value of that mobility. To many, it is worth the cost. So that if the Nxxx tablet and a given low-cost laptop cost the same (or even less for the laptop), and the laptop has more features and capability, someone will STILL purchase the Nxxx tablet because that mobility factor has value. Heck, I have and use both. They are not mutually exclusive. There is certainly overlap, but that should not completely preclude ownership of both. The differences are the motivating factor(s) that drive purchase.
