I've changed my mind about having only a handful of books on the device, since I've discovered the Calibre catalog. I never paid it much attention before, but it has a very nice layout.
You can browse the catalog by author, series, title, etcetera; enough to choose a book at least. After I've decided, I punch the last name of the author and a keyword of the title into the Kindle's search, and the book pops up.
I don't need any navigation on the Kindle itself anymore.
Since a few days I have all of my unread books on the Kindle, together with the catalog.
