How powerful is your cellphone?

After viewing the video the statistics provided in it are astounding and shocking, but completely believable. Everywhere I go I see people on their cellphones, at work everyone is constantly checking their phones for texts, call, emails, coupons, tweets, Facebook posts, anything you can name, and they seldom engage 100% in real conversation because they always have a distraction. I am amazed to know that more people own a cellphone over a toothbrush, especially with the price difference! I also don’t understand how their can be more cellphones than people. I understand the fact that some people have two cellphones for work but I didn't realize that so many people have multiple cellphones. I also wonder if they are counting all the cellphones sold over the years, because I know that for me personally I have about four old cellphones in my room just in case the one I’m using now breaks and I need a temporary phone for a while. In the future businesses are going to have to start using mobile apps and create websites that look good in the mobile view because a majority of people are only viewing websites on their phones.
