MobileRss is a Google Reader client fully syncing with the cloud service. Working much like the native mail client users can read articles either in a portrait or landscape mode.
There is quick access to sharing to social sites like Facebook, Twitter, email and so much more.
In the current release, there is no management capabilities (adding or removing feeds for example). However this will apparently be added in the next release.
There are options to only download images when WiFi is available for the 3G iPad users.
Certainly a tops app and highly recommended.
