It is just the way that the organisation of them seems messier on the Kindle, you can set them before sending the books to the device on the sony and then the way they are presented on the home screen means you don't have to mess around with various workarounds as seems to be the case with the kindle.
I guess thinking about it, there are definite benefits to the way the home screen is laid out on the sony once you get a lot more books on your device, but then again maybe the way amazon expects most people to use their device is by keeping the home page tidier by moving stuff back to the archive once you are done with it.
