Does anybody have experience with refreshed MacBooks? How do they compare to refurbished? Refreshed simply means the computer was returned and Apple repackaged it, correct? Would I find a higher probability for a dead/stuck pixels (possible reason for the return...)? The reason I ask: I may be purchasing a refreshed MacBook from my Apple Store tomorrow. Price is $1156 for the mid-range white C2D model. Thoughts? Thanks for your help!
