I think it's because of cellphones that we have the world in our pocket now. For me, it's the knowledge aspect that really blows my mind. I can learn a lot of things from different sources and apply it in real life without ever having to visit the place that the knowledge was founded. Now, we can also preserve our past history and not half it lost with the sands of time, as it was previously. The good definitely does outweigh the bad, in many aspects.
