Gave my old blackberry to my grandson so he could play games on it. 
I have no games on my iPhone and I find it extremely useful in everyday ways. Siri, which I thought would just be a novelty, is becoming my favorite part of the phone. It is so easy to add to a grocery list, call someone, send a short email or text, add appt. to calendar. Don't need to find my reading glasses, just ask Siri to do it. I have been retired since before smart phones, so I never used one for business.
Now my iPad is a different story, it is mainly for entertainment.
