I figured that once I had my iPad, there would be no use for a secondary eReader. I'm finding that I still use my Kindle 3 as much as I did before my iPad. It's not that's the iPad isn't a good substitute at certain times, but from a weight and battery life standpoint, I still prefer the K3. Anyone else still use a separate device for reading? And if you're now using your iPad solely for reading, how do you hold it for prolonged periods (couple of hours) of reading ?
