Walking and Texting

These days, its hard to run in to someone who doesn't have a cellphone with them. Whether they have no idea how to use it, or know every trick in the book, cell phones are one of the most commonly seen things today in American society. I recently read an article and watched a linked video on a topic I hadn't heard of as a problem yet. Texting and walking. The video portrays the dangers of walking while texting, which are amplified being that the video is set in New York City. Everyone you see is looking down at their phone. I found the video interesting, but it sparked the question of are we becoming too dependent on our phones?
Every step forward in technology is great, but it seems that now these technology companies are coming out with something new for us to be addicted to every day. The article stated that "more than 1,000 pedestrians visited emergency rooms in 2008 after they were injured while using a cellphone to talk or text". To me, that statistic is simply horrifying. If 1,000 people can be so taken out of reality to get sent to the emergency room with injuries caused by phones, than the problem is apparent. People have to learn to be less dependent on their phones before everything works through phones and computers.
What can we do to solve this problem? Is it a problem?
