Sven let us know that he has released ReadOnTouch PRO for the PlayBook. ReadOnTouch is a WebWorks based client for the popular Pocket-Client (previously known as ReadItLater.com but now www.getpocket.com) service. Pocket-Client lets you save content to read later especially offline. ReadOnTouch is a nice interface for the service which makes it easier to read things on the go.
If you are a fan of Pocket-Client or want to find an easier way to read content on the go check out ReadOnTouch PRO for $1.99 in App World. Hopefully the developer will add a free trial soon.
