I have a laptop, a smartphone and a Kindle. The smartphone screen is terrible for hours of reading. The laptop is too heavy and the battery doesn't last long enough. On the other hand, the Kindle's battery is as good as it gets. I hope to never be away from a power outlet long enough for it to run out of juice. It's very light and the screen size is perfect for reading. There will be many similar applications for the iPad that people don't even think about right now.
