melusina, I'm glad if I can help, though as you'll notice my app still leaves things to be desired I bought the Pocket Edge because I'm constantly on the move and was fed up with all my paper notes - after having tested the Sony eBook-reader as an alternative I was shocked and disappointed with the note-taking capabilities in that device: if you think the eInk screen on the Entourage Edge lags, try the Sony ones. I have quite a fast handwriting and almost all other eInk devices that allow you to write on ended up with just a few random lines on the screen rather than text. So if your major goal, like mine, is to take notes and bring them onto your desktop, I can only support your decision.
However, there ARE some negative things about the Pocket Edge and they particularly relate to the support issue raised by you - if you look through these forums, you'll notice that more issues are solved by the impressive support through the forum members (thanks, girls and guys) rather than the Entourage team. In particular, we all dearly miss the publication of the SDK - I would really love to try some hand-writing recognition directly on the eInk screen to further improve usability of the Edge, but ...
Nonetheless, I should stress that I'm happy with the device so far and even if Entourage should discontinue it for whatever reason, I'll continue to use it until it falls apart
