Hello all. I am new here and I am pretty happy I found this forum because I am in the process of buying an ereader but am very confused about the technology. I want to buy an e ink display device that supports as many file formats as possible and has all the latest bells & whistles, yet I keep seeing reference to dedicated content service and this has me the most confused. Does a device that uses this feature have to read books bought ONLY from the dedicated content service? Or can I put books that I have already bought elsewhere on a device that uses dedicated content service, provided the file format is supported? I really wanted to buy the Kindle paper white but I realized it does not support epub file format and I have a bunch of books in this format, so I looked at other e ink readers and noticed they either supported epub, or left out mobi, or one of the other more noteable file formats. I would like the reader to support all file formats if possible, although it seems that this is not going to happen. I would also like to be able to put files on it from other sources. I read about the Bebook Neo, and the Cybook Orizon and noticed that these two readers are somewhat of a couple of banditos in the ereader world and that they dont utilize dedicated content service. Now I know having a dedicated content service such as Amazon's or Barnes and Noble's is quite a nice treat since they both have huge collections of books, but I don't want to be forced to buy my books from these sources only. Am I asking for too much? Or am I asking for a device that does not yet exist? Thanks in advance for any help or advice.
