Just getting a chance to get on MR today, so I haven't had time to read up to current on the various threads I'm following. So if this has already been mentioned, then sorry.
I checked out the poll numbers on Kindle Boards about the screens and to my surprise nearly 1/3 of those participating indicated they either got a replacement or returned their PW due to bad screens. Considering KB is little more than a "yea Kindle" kind of forum, that is a significant percentage. Poll numbers in MR are pretty high for replacements and returns also. I doubt either of these polls reflect actual percentages as KB and MR don't accurately represent the entire Kindle community, but I've never seen this much of an issue with any Kindle before. I've heard the initial release of the K2 was problematic, but since I purchased mine months after release I missed all the forum chatter about it.
As I was typing this my 2nd replacement arrived. Time to check it out.
