I, too, do not see the point in emulating page turns and bookshelves for digital editions.
The website claims that converting Google books to PDF is the "ideal solution" for Sony reader, Kindle and Nook! PDF seems pretty useless to me on such small screens, unless you can control the format to create a PDF specifically for that size of screen. Can you do that?
And then there's that name. GooReader? Seriously? Are there a lot of people out there reading goo, or is this a product for babies?
