The article falls short on the comparison part. Why is the author comparing the cost of using a phone for a couple of minute to the cost of eating out that you usually do maybe once or twice a month? The duration should be similar. Following the author's example of buying a $1000 phone every 2 years, that would cost about $9.2 every week or about two McDonalds meals every month. If I'm given the choice between the two, I'd take the McDonalds.
