It's good that they did this for sure. I remember reading that people were also having problems with the rear glass shattering from the thermal shock of being placed on cold counter tops. I'd still probably get a case for it, though. If you have generally pretty dry hands like mine, a case can reduce the strain of holding on to a generally slippery phone. I also don't know if this would be changed by the little nubs but I had issues with it regularly sliding out of my pocket while on couches.
