Smartphones have truly improved my life beyond comparison. I still remembered the bad old days when I was young: * Too worried to take a picture because I might ran out of film. * Too worried about screwing up the flash light because I didn't have enough film. * Recording important things (like my class) was too big of a hassle and too expensive (Not enough tapes). * SMS was a cost that I always had to worry. * Books are much lighter now because they are now digital. * Podcast was such a hassle before because of carrying around tapes. * Laptop was a thing but nowhere as convenient as a smartphone to look up a reference.
