When your disposable income is less than US$x dollars
a month, your investment in even a “cheap” cell phone
becomes far larger than it is for someone earning a
living wage – and your expectations of the phone are
comparatively greater. You expect it to last a long time
in often harsh environments and also deliver high quality
voice capabilities – because you’re paying precious
dollars for air time.
