I haven't dropped mine yet, but it does seem to get very slippery after you get a bit of oil on it and it's difficult to clean.
Think I may go with the Seidio surface case just for some grip. I hate to do it because I told myself I'd go naked because of how great the Nexus looks, but I'd rather not be sending it in 2-3 times over the next 2 years for insurance claims. I can't see the screen taking many falls very well.
It just hit me, they(Samsung) charged you $167 for a screen replacement, but your phone is probably still damaged on the case itself.
But with insurance it's only $100 per replacement, you get a refurb of course, but I've found they are often tested better than new devices.
Insurance cost: $6.99 a month; $83.88 a year; $167.76 over the 2 year plan.
So with lets say, one replacement over a two year contract, I'll be paying $267.76 for a Nexus replacement heh. Your screen replacement doesn't look so bad after all when you lay it out like that.
