Phones are all about what fits you IMO... I need to really have internet and email ability in both my job and selling our Beef. I use the hone a lot to market our Beef. People ask me all of the time how I can do both (Actually, all three if you consider running cows and calves). It would be impossible if I didn't have a smart phone. That being said, not everyone is me trying to manage my challenges. If simple fits you best, buy simple. my iPhone is really a little mobile computer that lets me make phone calls.
One huge irony... When they started putting camera's on phones I was likely the worlds biggest skeptic. i don't know what I'd do without that ability now. A picture is worth more than a thousand words when you are trying to show something.
