Interesting discussion here. Many valid points made on both sides of the argument. But let me play a little devil's advocate here for a moment; what about a poet or author whose work full justification would completely ruin the style of his/her work? I am speaking specifically of one of my favorite poets e.e. cummings. Would you folks not read his work in ebook form just because some of his poetry does not lend itself to either right or left justification.
If you are unfamiliar with his writing style to see what I mean, check out this ebook verson of some of his poetry to see what I mean.
