Mark Zuckerburg famously stated that the iPad isn’t mobile (Parr, 2010). Jakob Nielson’s report suggests that iPad users don’t use their iPads in truly mobile situations, and those that do take their iPads away from home tend to use them in more relaxed situations (Nielsen, Budiu, 11).
Where does that leave your feature offering and user flow?
