Well, the title basiclly says it all!
I have a Kindle 3 Wifi, the 6-inch screen, and natively, the PDF looks terrible, as it's super small font and etc. And zooming is a total pain :P
I've tried using Calibre to convert the PDF --> MOBI/PRC = FAIL!
Reason: My PDF is a technical jargon pdf, with many diagrams and "pictures."
I also tried using PDFReader, the one made by the guy on this forum (Nick - whatever his nickname is) I used 1.8.2, and, no, it was small font again, and didn't work out too well.
Is there no hope?
Or should I just buy the book, as in non-e-book, like, the actual paper/binding book

I, officially love the Kindle, so I don't really plan on that...
And that's the story. Thanks everyone!

Or - can I email it to someone here who is "more-experienced" than me, or am I just asking for a solution to a problem that currently has no solution?
Thanks again
