Honestly, I'm now about the other way. Not being able to read my K3 outside in sunlight sort of defeats the purpose of owning it to a large degree. I either read outside when it's nice out, or while I am in bed. I can still do the latter, but I really like reading outside.
Since Amazon CS doesn't seem to want to help, the only course of action seems to be to return my K3 for a refund and wait for a Nook 2 announcement.
