Sorry, I know everyone here is using DR. I am also planning to buy one. However, when I go to amazon website, I find kindle DX is only 500 USD(=350EU only) and.... and it seems the kindle DX can be ordered from Europe too. So I hesitate which one to buy, because basically I just want a reader to read my academic papers and the screen of kindle DX is 9.7'', 824*1200, which might be fine for A4 paper.

More importantly, I can save a lot of a lot of money!!!!!!!!
Is a 9.7'' screen OK for A4 paper??!!!
