Google Reader for iPhone/iPad/iPod Touch
jReader Pro is a Google Reader Client. You could download it from App Store (the keyword is jReader Pro, search it through Apple App Store in iTunes).
It supports both iPad and iPhone/iPod Touch devices. Just install it on your devices, and input you Google Reader account and password, you could sync all subscriptions from Google Reader Server.
The user experiences on iPad is just like a book, and you could slide the pages of this book as you want. Just try it or see screenshot on App Store.
By the way, maybe you are interested in foreign languages. For example, you want to subscribe the news feed in Chinese or Japanese, but you cannot read it. With jReader Pro you could do it now, because it has build-in feature which support content translated into more than 50+ languages, and it's powered by Google Translate.
