Thanks to babaca, she's the one who sold me on ebook readers. One of the main things that sold me on Sony's is that, if I remember correctly, it's the only one that will take WORD documents as well as just about all the other formats. One downside, which doesn't bother me at all, is that the formatting in PDF goes a little wonky as you increase font size.

The added benefit, too, is the ability to be able to use external memory to increase the amount of ebooks you can have with you at one time. *grins*

All in all, I've now gotten no less than five people around me to change their minds about what a wonderful thing ebook readers are :)
