I was reading about the Asus Padfone and it got me second guessing some of the things I have written. Am I wrong that the phone will be primary with a wireless link to other display devices? Or… perhaps I am correct and these are just steps along they way. That happens when a trend is major as I previously discussed. The problem with my solution is battery life. What the Padfone brings is the large battery in the tablet. Having a full time high bandwidth link will require major improvements in battery technology. That will come but it isn’t here right now. Perhaps each device should be able to stand on its own. If so then what happens to my dream of the phone as the central device? It stays alive in a modified form. Rather than transmitting the display perhaps the devices are sync’d so each has the same programs and all that needs to be transferred is current status and data. This will minimize data transfer and hence battery consumption. Switching from device to device won’t be quite as seamless but the basic idea will be there. As battery technology gets better we will eventually reach full integration but right now we’ll have to be satisfied with incremental steps. As I’ve said before, this is going to be interesting and a lot of fun to watch.
