Motorola has developed a stand-alone media player, the DH01 device that works with the DVB-H mobile video standard and also plays on-demand video clips and programs saved on digital video recorders. Motorola, Nokia, Samsung Electronics and LG Electronics already make phones that can receive live TV streams. What is different here is that Motorola wants to gauge demand for a stand-alone video device.
At some point, the user desire for simplicity will outweigh the desire for multiple functions in a single device, even as designers work to simplify inherently-complex devices so they will support multiple applications.
Up to a point users seem to enjoy having multiple functions in one device. Email and text plus voice is one example, while voice plus text plus music provides another example. What is less clear is what happens when users are offered devices that add Web services, enabled by Wi-Fi as well as mobile broadband, as well as video. At some point, the cost of a "do everything" device starts to get pretty high, while the functionality has to be balanced, possibly decreasing user satisfaction as a multi-function device will tend to perform less elegantly than a purpose-built device.
The issue is that the range of applications people want to access is growing all the time: gaming, navigation, video, audio, radio frequency identification and sensor network access. At some point, the complexity overwhelms the user experience, which has to be kept as simple as possible.
The other issue is how much tolerance end users exhibit for higher device prices when those devices break, get lost and wear out fairly frequently. It might be one thing to expect replacement or loss of a $100 device. It might be quite another to risk the loss and replacement of a $700 device. With volume and time, the issue arguably becomes less pointed, as features found in $700 devices migrate down the product lline.
Still, some point likely will be reached where users simply find "do it all" devices less desirable than carrying a couple devices that are highly optimized for the applications those people want to use most.
It sort of depends on what sort of end user you are, as this analysis by Motorola suggests. Power users require more than lighter users, to be sure. The issue for a network engineer, of course, is that a network has to be engineered for the needs of the most-demanding user, not the least-demanding user. Which suggests that the supply of bandwidth will continue to climb, though it isn't so clear that power users will escape the requirement to pay more money for the privilege.
