I think DR 1000s is more flexible to read PDF file. However, considering its big price,

I have to make a decision between DR and DX.....
What I am concerning is that I mainly use the device to read academic papers, however, the font size of PDF can be adjusted on the DX (at least currently), so could somebody kindly help me try the attached PDF file and take some pictures if possible? The file has small font size, two columns, and small blank margin, which is very difficult to display.
The DR 1000s seems dislay very well, so how well on the DX???????
Thanks very very much.
