Very happy, this has some GPS, I played some COD Zombies, surfed, played music, listened to internet broadcasts, e-mail, Facebook, Texting, Talking on the phone, Banking, checking and researching 3 Fantasy Football teams all on different apps, Taking pics and video. There's more, but you get the picture, I'm a heavy user. I use my iPhone like this daily.
Normally I charge it at night so my battery is never dead while I am away from home.
