Beyond "hello world" and the recent clock hack, I haven't seen anyone compiling apps to replace the native reading app on the Reader (e.g., xpdf, HTML browsers, Simplereader, etc). There seemed to be more activity on this front for the Librie in its day. There were some comments about porting a Librie app to the Reader in
this thread, but there was no follow up discussion.
Are there hardware differences from the Librie that no one has quite figured out, or is there simply no interest in pursuing this path?
