> Does anyone know if there are any plans to add full PDF support to the orriginal Kindle and Kindle 2?
I doubt it. The Kindle/Kindle2 screen is 6" diagonally, and you just can't see an 8.5x11 formatted PDF well enough on a 6" 167 ppi e-ink screen. There are a number of mechanisms for converting PDF to Kindle's format already, and they're mostly free. You can send the PDF to [username]@kindle.com and it will be converted and delivered directly to your Kindle for a fee... Or, send it to [username]@free.kindle.com and it will be converted and mailed back to you, where you can copy it on via the USB interface for FREE.
The best conversions for PDFs with images / detailed or complicated formatting is to do something which involved converting the PDF to 1/2 page images and displaying them in landscape on the Kindle. There are a few options for this here at Mobipocket
