Yes, I have plenty of books to read on my Sony - just not the ones I most want to read right now. There are plenty of books that I want to read on my Sony but can't but I could if I had a Kindle. I don't want to buy pbooks and I don't want to buy ebooks in other formats and remove the DRM and shift them. I just want to buy the books I want to read and read them. Sony lags far behind in offering that service to me and other vendors are not filling the gap. So why wouldn't I gripe?
This will then lead you to "So why don't you buy a Kindle"?
