I was reading this thread

https://www.mobileread.com/forums/sho...t=21808&page=3

and came across a comment (#111) which implies there exists the possibility that eink screens can have their contrast degrade over what would seem to be a short period of time.

Is that the case?

I ask this because I did a side by side comparison between my Nokia N800 and the Sony PRS505:

my preference easily being the N800. But this was with a demo unit. Now I am wondering if there is a possibility the display has lost contrast over the time it has been in use in the store.

Just curious as it would clearly explain why my experience gave different results from what others report.
