Some number-crunchers figured out the true cost of owning a smartphone over your lifetime. They added up the amount of money spent on continually replacing your phone throughout your life, the cost of wireless service and the cost of apps ⊠which brings you to just over $75,000. If youâd put that money into an investment account that earns just 4 percent returns, youâd come away with $300,000. Thatâs a lot of money. But, itâs a small price to pay for the ability to check Instagram and play Candy Crush, isnât it? (New York Post)
