Is Kindle (Wi-Fi) or Kindle 3G (Free 3G + Wi-Fi) right for me?

Kindle (Wi-Fi) is a great choice if you already have a high-speed internet connection and wireless router set up in your home and do not need the added convenience of a 3G connection. 3G enables you to download books anytime, anywhere, while on the go. If you do not have Wi-Fi set up in your home, Kindle 3G may be a better option.
