1. The RSS app deletes articles before you have a chance to read them (if auto-update is enabled)
2. The RSS app deletes entire feeds for no apparent reason

Given the above, it's absolutely rubbish - it's also been fingered as a possible cause of reboot loops. The RSS app is seemingly designed to self destruct if someone sneezes - it's hardly a robust and well designed application considering it's high profile nature on an Internet Tablet.

I get the impression it was whipped together by an undergraduate student on work experience. And judging by the comments from Nokia in bugzilla, Nokia aren't particularly interested in giving it any care and attention.
