Never a truer word said.
Why do these people think that anyone working on a building site will need a bash resistant smart phone with less functions?
Stick with whatever phone you want and buy a decent case for it, Lifeproof, Otterbox or Gumdrop etc.
I work outdoors, go on site and have dropped my phone on a number of occasions, it survived.
This CAT phone is trying to solve a problem that doesn't actually exist.
