Really? How long do you keep your phones for? 2 years, tops? I've never damaged a phone I've owned, let alone rendered one unusable because of either dust or water.
This will have no appreciable effect on the life of the product for me.
"In all my experience, I have never been in any accident... or any sort worth speaking about. I have seen but one vessel in distress in all my years at sea. I never saw a wreck and never have been wrecked nor was I ever in any predicament that threatened to end in disaster of any sort." -- E. J. Smith, 1907, Captain, RMS Titanic
I'm less worried about icebergs and more worried about 3 kids under four, dropping it in a puddle (I live in the Pacific Northwest), and just dropping it in general.
