If the K3 doesn't get KF8, I may be time to move to a reader with ePub support. What they're doing with the DX is a crime. I would love to get a DX just to read PDFs, if nothing else.
I have no issues with touch screens, so I could consider the Kindle Touch, but I do demand physical page turn buttons, and I want them in the bezel.
I really like the new Sony Readers, but I hate the layout of their page turn buttons.
