The Kindle’s E-Ink screen is so much better for reading than the iPad’s backlit display. However, what I appreciate even more than the screen is the Kindle’s size and weight. The iPad is not comfortably held for long periods of time and is nearly impossible to use with one hand. The Kindle blows the iPad out of the water in this regard.
The way I see it, the Kindle is like an iPod nano. You can play music and read books on an iPad, but in an ideal world, you could read on a Kindle and listen to your iPod.
