I don't have an iPhone (although I have iPhone envy), but I have seen the Kindle app in action on a friends phone. Obviously the screen is smaller, but the clarity was excellent. My immediate reaction, however, was that the backlighting would make it uncomfortable to read for any length of time. So, based on not having an iPhone and a 10 minute demonstation of the app, I concluded that the iPhone is a nice supplement but could not really be a replacement for the Kindle. How's that for jumping to a conclusion with limited evidence? Thoughts?
