Engadget - Not every smartphone stakes its claim on speedy processors, huge gorgeous screens or slim and sexy physiques. Some take a relatively modest set of specs and add a little wrinkle to make them stand out from the crowd. The Samsung Rugby Smart is one such device. Though it adds Android to what we'll now refer to as the Rugby Dumb, we can already tell you this handset isn't for the spec snobs among you. But, if you're more concerned with durability and tank-like construction, you might want to stick around a while.
