Remember that the Rev A and B 12" PBs came with a different screen than the rev C and D. Since I have a rev B, I have an even worse case than many of you!
And colour correction and calibration doesn't do enough.....
Yes, I did use SuperCal, but calibration isn't magic. Its not going to make your screen brighter. It may make the colours look less washed out, though, and that's exactly what SuperCal did for me, and I'm happy. 🙂
