Well, this looks like a good idea in terms of time-saving automation, but it also opens an individual to more hack attacks, and, I would think, has serious ramifications for artificial intelligence as an assistant. I am sure that the Butlerian Jihad in the Dune book series is now a branch probability in our timeline.
The new Leaf+ system for SunnyBag is one that I wouldn't mind having. Since I usually have at least one mobile device with me, having the option to keep the power up while traveling around the city is already a big come-on for me. The real use for this, however, would be for hikers and, perhaps, mountain climbers - anyone who wants to go to the great outdoors, but have the option to take their devices with them.
We shouldn't be surprised that all tings will go mobile. After all, we started with static tools, like PC's, then went on to laptops, and now to mobile devices. I would not be surprised if one possible branching of our technology would be to incorporate generic terminals or even a supernetwork and server system so your body carries a profile identifier chip and cybernetic implants, and you just plug into your own "virtual world/desktop" from anywhere there is service. At that point, having a modile device would seem positively archaic.
... and I just realized that I described part of the world shown in Ghost in the Shell.
