This should be a feature of all phones. There's nearly zero number of times I want my phone to move from where I've placed it.
AT&T has a phone that's some serious shit. We got a demo the other day... and that thing resists drops, high temps, freezing, water splash (or underwater to a couple of feet... don't remember).
It was some serious hardware. Of course, it's not running Android, yet if you want indestructible, I was impressed with this thing.
Me, personally: My phones last approx 2 years. My iPhone 5 (got it around 1 year ago I think) is all busted up. I'm not an Apple lover, yet this thing is tough. EVERY panel on it is broken, bent, shattered... and it still works without a hitch. Props to Apple on that.
My N9 is well over a year old and has zero broken external parts. And of course the phone itself still works.
Given that a smartphone has virtually no moving parts inside, continued functionality absent being submerged or crushed is not a particularly noteworthy achievement.
