I got a the new 505 reader from a physical sony style store last Saturday and so far like the product. But noticed a smudge/mark on the screen that I can't work out if its damage or not. See below for some photos. It's not immediately noticeable and could have been like this since bought it. I certainly haven't dropped it, placed anything on it or even put it in a bag, so if it is damaged I didn't inflict it.
So my question is whether or not this is real damage or just a "feature" that will disappear over time? As I got it from a sony store I would imagine they should replace in then and there if I have an issue, although reading some of the other posts about sony's customer service record I maybe wrong
