Yay, I finally got my PRS-505 e-Book reader! I fed it with a couple of e-books from the Gutenberg project and its German affiliate, and I’m very pleased with the display and reading quality. Now I can finally take something to read with me again on conference travels and other occasions when I don’t want to have lots of luggage.
Now that I can actually try it, I found that my initial packaging of calibre was pretty incomplete, it didn’t detect the reader at all. Now I added the missing bits and updated it to the latest upstream version (see my PPA). It’s working out of the box now for the PRS-505.
