Kay compares the iPhone, et al to "selling sugar water to children" in an attempt to relegate them to "consumer gadget" status... compared to what, enterprise gadgets?
Whether or not one outweighs the other, or whether the latter is all that bad, is a different discussion. But just because you have a different perspective than he does is no reason to attack him for it.
And he calls it "sugar water". Baffling.
