Pulse News Reader is one of the iPad apps I use and now it has become a free app for the iPhone and the iPad, so now everyone can enjoy its greatness for absolutely nothing!
I find NetNewsWire and River of News (iPad) work well together. Pulse I keep for the daily papers and weekly periodicals.
Then theres also Blogshelf for blogs and.....Reeder and Flipbook...
Rather than stuff everything into the one app I find it helps to divide catagories between apps, but then I do like eye-candy.
