I prefer to use my email clients to read my news. Means I don't have to run an additional application. I have a script which monitors RSS feeds and turns them into emails. I filter them into a "News" mail folder. I run K-9 Mail, Mutt and Webmail depending on what device I'm using. Thanks to IMAP my "news readers" stay in sync due to the "\Seen" IMAP flag, and the ability to delete messages. Thanks to IMAP PUSH I don't have to poll for new RSS items on my various client devices. Thanks to IMAPs subscribe I don't get News on devices I don't want it on.
[edit] I use sieve to filter real newsletters into the same "News" folder, so it's a mixture of content from RSS feeds and newsletters.
