I am always on the hunt for a better Google Reader experience on both my BlackBerry smartphone and PlayBook. The latest I have found is Web Reader for the BlackBerry PlayBook and I have to say I am impressed. It does cost $4.99 which puts it in stiff competition with the capable and free GeeReader app. Still Web Reader does hold its own with some pretty cool features that simply look good.
You can check out more about Web reader on their website or pick it up for $4.99 in App World. They also have a blog post up about their aggressive memory management that should make the app run smoothly.
