Thanks very much Mike, I did convert some pdf-s, and the conversion seems quite reliable.
A typical article that I am reading is:
http://www.math.purdue.edu/~arshak/p...energ-corr.pdf
Of course, for the articles available in ARXIVE, I do get the latex source file, and there is a special latex style that one can use for different e-readers. But unfortunately most of the papers in my direction are not available there...
On a side not thought I am not sure about how it would actually look on the screen...
I mean to me it seems that the conversion is basically a scaling process, in landscape mode you have the feeling that too little is shown at a time, and you have to scroll to often, and some of the fonts might look too small in portrait mode when actually shown on the device. It is too bad Sony does not sell them in Europe, so I can't check it in a shop... (while I can ask my brother to order one in US).
Thanks again,
Norayr
