Federico Viticci has a detailed take on the transformation (?) and states:
Unlike Weiner’s previous attempt at solving the “save for later” puzzle, Pocket is immediately visual, making it extremely clear that it wants to be a place where you save “stuff”, not just articles.
I think thats a good description. Pocket feels more like Yojimbo in the cloud to me, than it does a good read-later service. Yojimbo may even be a poor comparison, Flipboard Pro may be a better analogy.
