I just switched from a Rev. A to a Rev. B 1.86 128gb SSD. On my Rev. A, the backlit keyboard got brighter as less ambient light was present, the new one dims in low ambient light and brightens in bright light... is there any way to fix this? Also, the backlighting of the keys is very uneven such that it's really bright around the edges and quite dim in the center of the keyboard. Is this normal for a Rev. B? Should I bug AppleCare about it?
