Dead, errr, balls?

[heb]

Is it usual for the screen to have some very small black dots on it? I think they are actaully smaller than individual pixels so I am guessing they might be the individual little balls used in eink display. I am guessing they are the equivalent of dead pixels on an e ink display. They are only visible in bright light or if you are looking at teh display very closely.

To be honest I am not sure if they have always been there and I just didn't notice them in the first could of days or they have developed as the reader has been used.

If it isn't a fault does it gradually keep getting worse? At the moment it can be distracting but its not making the screen unusable.

Thanks,

Richard.
