This phone was like that for me (maybe not for you!). I was seriously addicted to the Internet, like seriously browse HN and reddit for a couple hours a day everyday. Youtube maybe a couple more. Now unless I'm working or streaming a movie I rarely even open my laptop and it just sits in a cupboard. My life has drastically improved after working to rid myself of Internet addition. It's a serious problem for many people. Getting a phone where I could remove the Web from it completely was a huge part of that.
