I recently got a Kindle Touch. Why not the Kindle Fire? Well, my wife pointed out that if I got that and then later wanted a more high-end tablet that she was going to be hard to convince. Plus the idea of battery life measured in weeks rather than hours appealed to me.
So I got the Kindle Touch 3G on the theory that I hate running out of books to read on the train. So now I can buy a book on the train, and have more waiting besides.
Getting to the browser part, while you wouldn’t want to do a lot of web browsing on it, the Kindle Touch browser does do Wikipedia, not to mention this web log, thanks to the highly-recommended WP Touch plugin.
