I've been a Kindle user since February, and love it. One big drawback: multi-column pdfs are nearly impossible to read. I just sent myself a .pdf with the word "convert" in the subject (through Amazon's service) and it turns each column into a page... so you can read the pdf just like an e-book. Obviously, formatting isn't the prettiest. But it is readable!
The big deal for me, is that I can significantly reduce paper clutter: no more printing up reports to read on the bus. Just e-mail to my Kindle.
Looking forward to the new firmware update
