If your e-mail on hte Mac is like the one on the iPad, try River of News RSS reader. It looks similar to the Mail; there's a left column showing all your feeds while theright-side column allows you to scroll throught the feed headlines. When you see a headline you like, pressing on it opens a full-screen in-app browser so you can read the article.
As you probably can tell, River of News is my favorite RSS reader and it's what I use daily. Of course, and as always, YMMV.
