Is an iPad a computer? Is a Microsoft Surface a tablet? What about Chromebooks – how do they fit into user’s uses? The major tech marketers are working to shift perceptions, such as Apple’s positioning of the iPad as a computer. Even though perceptions do shift buying decisions, user innovation and inertia are a force to reckon with. Many users have already pioneered ways to use their devices. We went straight to the users to see if they’re using tablets and notebooks the same, using iPads differently from Android Tablets, and Windows Notebooks from Chromebooks. Our basic hypothesis is that perceived differences, if substantial, can be confirmed by measuring user behavior.
