I just noticed my screen fading for the first time a couple of days ago. I usually sit in the shade, but as I was walking to the mailbox and back the screen faded.
Not sure I can part with my beloved PB302 long enough for a replacement though. Since I just noticed the problem after having it for a few months, I think I'll hang onto it.
Besides, we only have 3 months of sunny weather a year in Seattle anyway
