Many words but he's entirely missing the point. All these comparisons completely ignore the difference between gadgets and platforms. A platform is nothing without many third party softwares that run on top of it. Phones or MP3 players are gadgets that come with the main functionality built in and don't need any third party software to be useful. Their usefulness depends on how well these core functions are implemented and not much else.

The role of DOS or the Mac simply doesn't exist in the mobile space and therefore these comparisons are meaningless. Mobile platforms don't exist. Phones are just gadgets and smart phones are gadgets with optional addons.
