Everyone who spends money beyond the ascetic-level can be judged by others. Many of us buy new $650 phones every two years, which I'm sure seems incredibly wasteful to people in third-world poverty.
For reference, I do practice such things. My entire computing and mobile outlay has been about $250 in the last 5 years.
That's more than some people make in a year.
Not sure why I'm feeding you but there it is.
