Not in my experience with 18 months of owning the 505, at least not to the level the OP mentions It's a bit lighter maybe, but not "hardly readable. Letters are missing and there are large white areas on the screen."

And that includes numerous hours spent on a lounger on the solarium at my parents house in Spain. Or while "watching cricket" with the rest of my family in the summer.

(By watching cricket I mean sitting quietly reading with a drink while the rest of my cricket obsessed family watch or play, the 2nd most boring sport, to watch, in existance. The first being Baseball).
