The Smart Phone Is Taking Over

When smart phones appeared first on the market I was not impressed. Ok, I saw you can use them as a mini-computer to browse on the net, read your emails or chat on the go, but apart from this I didn't see any killer app that would make my life easier. I'm not into gaming, I'm not into photography, so having two cameras or a processor that can run whatever game was not touching me at all. The first application that convinced me to buy such a phone was Google Maps (or any other maps) combined with GPS capability. I didn't have a GPS at that time, but I was considering buying one, so when I found that I can do the same thing with a phone I just bought the phone. The smart phone just killed an entire market of GPS devices, their only niche at this moment are the car companies where they can get deals to pre-instal their devices.
Now and then I find an application that can really help me with some task. If you go to a baby expo you will see countless of systems to track your baby if she sleeps in another room for example. Not needed anymore, there are application for your phone like Baby Monitor which can do the same thing and call another phone if your child starts crying in the middle of the night. Two days ago I was in line at the pharmacy and as usually I didn't have the fidelity card which gives you some discount with me. The man behind me at the queue told me that there is an application (VirtualCards which is tailored for the Romanian market, but there are others too) where you can store all your cards. It generates the same bar code as the one on the card and you can scan your phone instead of the actual card. Bang, you don't have to carry all those cards with you, the phone will suffice.
So if you know other cool applications for the phone let me know, I'm interested in simplifying my daily routine :)
