Dominique Bonte, who comments here every once in a while, posted his view of how the mobile world is changing:
The first model addresses the (slightly older, slightly less IT-knowledgeable) mobile professional who needs to be fully connected all of the time but who uses his mobile device for important but rather small/punctual events (reading or sending e-mails, looking up specific information on the web, using GPS-location to find destination,…).Ease of use is of major importance: no time can be lost in setting up or connecting devices. Performance and capabilities are balanced against integration and ease of use.
The second model is more targeted towards a younger, more consumer and family oriented target group, arguably less well defined than the first target group. This second target group has a much larger and deeper set of needs. Mobile multimedia entertainment is key: high quality imaging, video, music and gaming on the go. At home internet browsing has to be a transparent experience (large screen required). Large amounts of text input for e-mail, chatting, blogging require a full sized keyboard. According to these different modes of use either only the smartphone will be taken, or the smartphone in combination with the tablet, or only the tablet, or the tablet and the keyboard depending on the degree of mobility needed, the tasks to be executed or the comunications networks available. Customisation is key. Performance and capabilities come before anything else.
