Smart Phone. Smart Owner?

I was on the bus the other day, minding my own business, overhearing some people talking.  (okay, I wanted to mind my own business, but they were sitting right next to me and talking very loudly)  What really caught my attention, other than tales of drunkenness, was that one of them claimed his cell phone bill was more than 200 dollars.

More than 200 dollars!  Is that really possible?  Was he calling the International Space Station?

Granted, we are talking about a smart phone, so this bill includes some sort of data..... but still.  Is everybody out there running up these whopping phone bills?  Are all of you paying hundreds of dollars for the convenience of sending text messages, and checking twitter messages?  (Couple this with the cost of some of these smart phones, at least I can understand why we call the phones smart......)

Honestly, I am not a big fan of cell phones.  I am not unaware of their advantages.  I am also not unaware of their coolness factor.  My problem is less with them and more with the owners.  Is the information being conveyed really worth hundreds of dollars?  Is what you have to say, and who you have to say it to, really worth so much money?  Just asking.
