Tod, my partner in ThingM has written a great analysis on his blog of how ubicomp will permeate everyday technology in the near term, and how adding technology changes how we relate to, and how we buy, everyday objects.
As technology suffuses more into everyday objects, those objects will exhibit the same price elasticity of gadgets. Many domestic objects already do because of luxury and designer brands. The difference in comfort between a no-name leather easy chair from Target and an Eames lounger from Design Within Reach does not track the 10x difference in cost. The cost of adding intelligence to the DWR chair is the same as the sales tax on it.
I think he's right on, and he concludes with the most succinct statement of ThingM's philosophy to date:
Exploring what will be possible in a decade’s time is a useful and inspiring task. But until we have nanoassemblers, if we want to impact the lives of people today, we must discover and utilize the technologies available today that are on the verge of having high economies of scale.
I recommend his whole post.
