Most of the RSS readers for the BlackBerry PlayBook lack on options and the option to sync with google reader. Feed Wheel is one of the most advance RSS reader I’ve come across for the PlayBook. The application lets you sync with Google reader and it also syncs read messages.
What I really like is the multiple reading style rendering options that allows you to view the article in web, rss, and split mode. The web mode also allows you to play embedded media. You can also mark messages as read for all the feeds or within a single feed.

Feed Wheel is an RSS reader with a twist, literally. Feed Wheel lets you scan through your articles using a good old fashioned scroll wheel. If that’s not your thing, you can still scroll through news the way the kids do. You can also customize your hand position so that the scroll wheel and the control buttons are easier to reach. And to make sure everything is synchronized back at your desk, Feed Wheel can optionally synchronize with Google Reader.
I did find some problems with it where it does not sync all my Google feeds but overall is a really good looking RSS reader.
