If you've loved iPhone, get it. If not, then no. It's up to you.
Had this phone since it came out and it's amazing! Especially the camera and touchid. The only gripes I have would be the battery life and it's size which are both related due to it's smaller size with other phones now-a-days. It's kind of unfortunate to compare a smaller phone (and therefore smaller battery) to a larger phone with a larger battery. Other than that, iOS 7 looks amazing and it was due time for a change.
