Father and Son

The old and the young, my good old phone on the left my son's phone on the right.
Mine has no camera, no colour screen, no music and no poly ringtones. However, it's 4 years old, it's been half way around the world, I've dropped, it sat on it, kicked it and even forgotten it once or twice but you know what?

It just works every time every day.

I can't operate my sons phone!
