Annotation has always been the key differentiator of the eDGe from any other ereader (that and the dual screens of course). Clearly annotation has to work really well (for as many people as possible), so I look forward to enTourage refining it. They are somewhat hamstrung by the Adobe software they use for the Reader, but they've already resolved a couple of issues with the help of Adobe, and hopefully they'll be able to continue to do so.
