Google Reader for Android gets Honeycomb support1
This may not be the biggest update, but it's certainly a necessary one. The official Google Reader app now has Honeycomb tablet support to give users a native tablet UI to use while browsing their news feeds.
The Honeycomb UI is slick and clean as you'd expect, featuring a setup much like the Gmail tablet UI that we've come to know and love with the news list in a column on the left, and the article content on the right. It's a great improvement, now we just want to see Google add a night theme to the app.
