Google Translate for Kindle. One of the best features of the Amazon Kindle is the ability to access the internet virtually anywhere for free.
Since there is no touchscreen, the interface can be a bit difficult at times, but for simple errands like checking your email, reading up on something on wikipedia, or sending a text message with google voice it's great. For example, I step off the plane, switch on my Kindle and a few moments later I can send a SMS saying that I got there safely. It doesn't cost me a thing and it just works.
