I am in the market for a new case (disappointed in Commuter & need to switch). I'm seriously looking at Speck Candyshells & am trying to decide between Grip or Satin models. I was leaning toward Satin but I've seen a lot of buzz about the "satin" coating wearing off the shell too easily and quickly (even reviews posted on Speck's website). Anyone know if Speck has addressed/resolved this issue? Also, any advice from those who maybe have experience from Grip & Satin models?
