A bit off-topic, perhaps, but this article illustrates the difficulties that large corporations have with long term visions, especially in cases where sustainability has to compete with profitability:

I think the drive to focus on profits and what "consumers" supposedly want in corporate environments tends to undermine projects like these, even when the work is being done in part of an organisation that is supposed to be shielded from commercial concerns. Because conventional wisdom suggests that the public won't buy modular phones, no modular phones are made, even if there might be a demand for them if they were made. Indeed, just the availability of modular phones might drive demand for them.
This suggests a lack of imagination on the industry's part which I think is shown by the example of a phone module given in the article: a tiny "aquarium". Very interesting, but not really something that would sell the practical benefits of modularity. Of course, you need examples of what the system can do, but it's often the case that the most interesting ideas come from third parties. Just getting the devices out there with open specs and documentation would be enough to find the interesting use cases.
Anyway, this is only sort of relevant here, but I hope it was thought provoking. ;-)
