Sony connect software.....
original :"Less said about that experiance the better."
What I meant: "Less said about <edit>my book/connect software experience's</edit> the better.
"
The easy way to get things onto the reader is to put it on a SD memory card "same as most cameras, and palms use", and then put the card into the card port on the upper left edge of your reader.
Though I will admit the connect software works like a charm for books you buy from sony.
P.S. If the books are DRM'ed what igorsk said.
