I use my phone for 3 things. Phonecalls. Music. A few offline apps. I don't text. I don't surf the web. etc. So anyone else doing this is either doing it because they have to which means it's business and its deductible, or because they want to in which case you pay for the luxuries in life.
“That's it. You people have stood in my way long enough. I'm going to clown college!”
