Query: Kindle edition November, 27, 2010. A rip-off.

The format in a Kindle DX is awful, unreadable. Lines of different lengths, with one or two words, words broken at random points... Don't waste your money on this, it is just a pity that Kindle users do not get the respect they deserve. Buy this on paper or do not buy it at all.
