You need an ipad client, thats where a lot of content consumption happens, especially long form.
One feature which i really like about Pocket, is it saves a parsed copy locally on the ipad.
So i can "save"/ clip a bunch of links/articles, i want to read & then i can read them later, even when i dont have internet access (e.g. on a tarin/metro)
Very impressed with the product. All the best.
