I haven't tried the web browser yet as my sole purpose for buying the Nook was to read books. Please update us when you find out. Thanks.
Well, I've tried the browser on the kindle 3, and it is, um, functional. Works well for going to the Amazon site and perhaps downloading a book. Email and web browsing is a mixed bag. It connects fairly fast, but the keypad on the kindle is probably best actuated by a mouse standing on its back feet doing the rumba. A little small for my work-worn hands. I believe from past cell phone experience, that a person's best bet with a nook or kindle to web browse or download books would be when the train is in a medium sized or large town. Cell signals are usually readily available where the people are. I don't expect much rolling through the desert, etc.
