Its pretty easy. You can just transfer it by USB onto the Kindle. The updated software (either 2.0 or recently released 2.5) allows you to organize things into collections which tames things. The real problem is that you can't edit them. You can annotate them but my understanding is you can't annotate all PDFs. One of the principle reasons that I just picked up the IPAD. BTW Kindle software works on the IPAD.
