I share the sentiments expressed by sveral here- e-ink ereaders are great tools for reading. I avoid paper books because of physical limitations and avoid audiobooks because of an aversion to them, so e-ink ereaders suit me. They also illustrate the value of single purpose tools when done well. My tablet and my phone are multi-function tools could not be without, but for reading, just reading, my ereader is best - for me. Having a device solely used for reading is nothing new, since that definition also fits paper books.
