I wanted a small device and DXG wouldnt do it for me. Also there is the price difference.
The documents I want to read are scientific papers in .pdf and with two columns format. If I send them via mail to my @kindle.com mail they convert but some words get cut off and Tables get all jammed up. It is not 100% unreadable but if in every 2-3 paragraphs you have a sentence that is not full, you lose a lot of information.
