I ended up with the silver one. Still need to order the case. I've got The Sony Reader Library & Calibre set up on my Mac at home & XP at work. Took awhile to figure how to download from smashwords & get it on my reader. I found calibre to be the most intuitive & therefore easier to do this with. Downloading from the Sony Store the Sony Reader Library was easier.
So now I start reading my two new books.
