thanks aidren! Ive read the other thread and it makes sense (somewhat anyway...). I seem to remember that there are various other pdf 'readers' generally available, at least there's lots of talk about them on the pocketbook forum on mobileread. I think on the pocketbook they can choose between adobe and a 'free' pdf-viewer/renderer when opening a pdf. pocketbook ereaders run on linux though, so I guess that particular reader won't be compatible with the edge. But, theoretically speaking, something like this should be possible for the edge, no? Oh, hang on, I guess all the annotation funciton are build ontp of the adobe viewer...hmmmm....*smoking brain*
