I can read a PDF fine on my cheapo Sony PRS-300 ereader (text size adjustability and Table of Contents) yet when I copy to my Kindle DX 1st gen the TofC is gone and I have no ability to adjust text size besides using Landscape mode. Conversion to mobi is usually a disaster with lines missing. Is there any format I can convert the pdf to so it displays properly on the Kindle? And why would they sabotage such a great reading tool by making it not work with the most common reading file format on the internet? Because they want to get people to just buy from them? What about converting PDF's to the Amazon format (whatever that is)?
