I think a preference (or non-preference) for LCD vs e-ink is individual, and people should buy what they like!
Personally, I am nearsighted and usually take off my glasses to read. As a result, I hold the text fairly close to my eyes (around 10 - 12 inches). When looked at Nooks Tablets and Kindle Fires in stores in early 2012, I felt like I could see every pixel in the text. E-ink is much better for me.
