I guess we don't think of modern phones minimising interest in abstract products. The list of obvious products they have replaced is immense already; sat navs, cameras, camcorders, MP3 players, diaries, alarm clocks, calculators, radios, PCs(?), notebooks, watches, portable games consoles, wallets, cash (car park paying apps etc), newspapers, magazines, books, audiobook CDs, tape measures, encyclopaedias, stopwatch, and I could go on for some time.
Can you think of any that I have missed?
