I am loving the fact that Google Reader clients for the BlackBerry PlayBook keep on popping up. The latest is by the same developer of AIR Browser, Nicolas CHAIX, that we just mentioned. The app claims to have some offline capabilities and kind of works once you open a feed it will be available without images offline. It is not the most feature filled Google Reader client but it does work. I really hope the developer keeps working on it by adding features like marking all as read and only viewing unread articles.
