Rugged devices occupy a curious niche, generally falling into one of two categories. You have your consumer-klutz grade approach, which takes a "normal" phone and tacks on a bit of added durability to weather splashes and falls -- consider the Samsung Galaxy S5 Active . And then there are behemoths like the Sonim XP7, a tool purpose built for survival.
The Sonim XP7 stands up to the elements without sacrificing performance, but you'll need to decide if its durability is worth its premium price.
The Sonim XP7 will take just about anything you can dish out. It has stellar battery life, a versatile display and useful connectivity features for workers who brave the elements.
The phone's premium price and bulky chassis will make it a tough sell for those with more modest needs.
