I have read of the Cloud Collections problems, but I guess I need to experience it to find out how bad it really is. From what I have read there is just one 'nag' if you aren't on WiFi at the time you add something to a collection, and I gather that you can not sync non-Amazon material to their cloud storage; is there more to it than that? I do have more than a few books on my Kindle 3, and I don't get all of my books from Amazon, either. When books are transferred to the PW when I first register it, will all of the collections I currently have set up on the K3 disappear? If so, not nice......
