I am also a reader, however. I like reading. I also have 50-something eyes that spend many hours on the back-lit treadmill. So, the last thing I want in an eReader, the last thing I want in my Kindle is a backlit screen, the distraction of anything but reading of the words on the screen. What I love about my Kindle is that it is a dedicated reading device.
The following blog about the Kindle DX 2 gets at this very issue. It is worth a read, especially if you're a reader or techie who has been waiting to buy a Kindle until it is backlit, has a touchscreen color screen, or accesses the internet as well as an iPad.
