I've been considering getting a Kindle, but I'm not sure if I would really need the 3G capacity (to justify spending $50). In terms of technology, I keep things pretty simple...for example, I just have a standard cell phone (don't use the internet or texting on it). So the only benefit I can see of 3G is downloading a book outside of my home or using internet wherever. Are there other reasons to get 3G over not getting it?
