I don't really think that 'internet use' and 'properly rugged' are compatible.
As soon as you put a screen that is capable of internet navigation on a device, the device is vulnerable.
I have a water resistant (to being submerged standard) phone. The screen is still vulnerable to bangs and bumps. Any phone with a touchscreen is going to be vulnerable.
Phones that had buttons were physically tough and stood up to drops, but gummed up.
