I got the S4 Active which apparently became more popular than Samsung expected. I read it inspired the "ruggedized" direction the S5 went. I'm not too sure sure my definition of rugged is the same as theirs but it's held up well so far which has included my Bullmastiff pup having a go at it. I like the dust protection and fact it can get wet but I won't be submerging it on purpose. I hope this eventually leads to a truly rugged/waterproof smartphone at some point.
