There's some wisdom in the overall point, but the example of a mobile phone is completely upside down. I for one don't want to think of pulling a device out of my pocket in terms of some kind of microtransaction. Rather I want it to be a natural extension of my own mind, including running software that serves my interests rather than corporate spyware.

Of course one is always able to do a post-facto "price per use" calculation, it's just an extremely myopic paradigm to be thinking in. Even $/month is too small minded - that's how salesmen push you into paying way too much and financing things. But thinking $/year starts to make sense, letting you take into account things like how long upstream software is going to be supported etc.

Also yes, most everybody knows the tabs for eating/drinking out add up to a considerable amount of discretionary income. Those too are better brought into the $/mo and $/year paradigm.
