I am wondering since I think I see the first signs on aging on my 500 mhz dual USB icebook (first model after clamshell ever) It seems to me .. And I may be crudely childish in this .. That the screen is illuminated by mini neon tubes which are on top and bottom of the screen ... Like this - - - - - - - - - - So ... No, one, which is will mark as X seems to be dead .. As that sector of the screen is now noticably darker ... Albeit still not too annoying .. - - - - - - - - x - Is there anything to that theory or may that be something very else / fixable .. I am happy to say that my ancient clamshell (hey, Dan :) is still working superfine P
