application sector, the e book, and we name checked Mirasol bistable displays as a potential future game changer. In passing, we waxed lyrical about MEMS-based devices including SAW and FBAR filters, gyroscopes and accelerometers and (potentially) as a replacement for quartz crystals in resonant circuit design but suggested that the rate of innovation in the RF component sector remained a problematic constraint particularly in terms of multiband mobile broadband connectivity capability. In this final chapter of this section we have briefly reviewed the evolution of the HUGE TV and the potential impact these devices will have on the technology economics of delivery bandwidth and memory bandwidth added value. Which brings us on to the next five chapters and the topic of user software value. Part Two User Software Device-Centric Software 7.1 Battery Drain - The Memristor as One Solution The last six chapters have looked at how user hardware influences network value and user value. The end point in the last chapter was smart televisions and 3D-capable high-end lap tops. If it was just one application being supported at any one time then life would be reasonably simple but in practice there is a user expectation that the device and the network to which it is connected should be capable of supporting multiple tasks simultaneously. An example would be a lap top or tablet user texting or sending e mails while watching a video on You Tube with a Skype session going on in the background. Then the phone rings. At this point the weakest point will cause some form of instability that will become noticeable to the user. This might be caused by a processor bandwidth limitation, a memory bandwidth limitation, an interconnect limitation, a network bandwidth limitation or an energy bandwidth limitation (the battery goes flat). For example, the lap-top user forums referenced in the last chapter are mainly focused on how to disable functionality to reduce battery drain, which rather defeats the point of the product. There are potent
