I've read threads like this with interest for a while now and was soooo close to clicking 'buy' for a DX for my academic reading.....until I transferred the PDFs to my K3. Unfortunately some came up with a message that some PDF functions are not enabled etc, and this is with the K3 having a later firmware. I can't take the risk of buying a DX and only have some of my PDFs work. These are standard PDFs, just dual column academic journals.
Looks like I am back to printing them all out
