The Kindle includes a very basic web browser that uses Whispernet (Sprint EVDO), but it is essentially a dedicated ebook reader. Its 6" 4-greyscale screen (portrait mode) is as wide as a N810 in landscape mode and twice as high. So one Kindle page equals two FBReader N8X0 pages. One downside of E-Ink is that refreshes are slow, so zooming and panning isn't really an option. So the smaller N8X0 can be better for reading standard sized PDFs (which have to be converted for the Kindle anyway).
