WOW. Thanks Travis, for turning me on to this app. I've posted in the past about my frustration with news readers. I've never found one that I consider to be perfect. So far, I've found Newzie to be awesome. Literally every time I find something to complain about I find it has some method of doing things that solves the problem. It ranks posts by most recent and still shows how many are unread. It has multiple ways to consolidate views, it can be reduced to just a slim panel or even a ticker. It is not intrusive nor does it bog down your machine or connection. The interface is clean and mostly customizable. It even does interesting things like show how many feeds you read per day, etc.
It doesn't really have a great method of dealing with attachments on an automatic basis but I've basically decided there is no good program out there to handle attachments (including iTunes, I tried it too). I'm looking for something that separates audio, video, photos, and files, deals with setting metadata and creating playlists, and manages archival well. So for now "Save as Target" within IE RSS is still working fine.
The only two things I wish I could improve are moving "mark all as read" and "delete all" off the sub menu when you right-click a feed name, up to the first set of menu choices. I also REALLY wish it would integrate with the Vista central OPML.
