AppleInsider published an insightful article on the advantages of distraction free reading and how easy it is to put Instapaper or Pocket to good use in this regard.
This has happened to you. While you’re very busy at work or on a project, you somehow come across an interesting article on the web and you just cannot read it yet. Certainly that’s at least partly because you’re conscientious and you know you’re busy, but there’s more. If you read it now, you would hurry and this is something you want to actually enjoy. So read it later instead. Find this piece on your Mac at work and then read it later on your iPad. You could bookmark things but get Pocket or Instapaper instead.
