Looking forward, ePub is the most significant capability of Adobe DE on the PRS-505, but don't forget that it also supports all existing Secure Adobe ebooks. I have had bad things to say about Adobe ebooks in the past, because they keep changing the ground under readers who just want access to their legally purchased ebooks on new devices. However, Adobe Digitial Editions appears to be a viable and stable platform for ebooks and there are probably more Secure Adobe ebooks than any other format.
