Idea for a blog: whydontwehaveityet
IgorCarron: It's a very nice idea actually. I'd contribute to it. What happens in most cases is that that one of the party (researchers, PR, ....) has oversold the potential product in the first place. Another part of the story is that in the process of maturing, or increasing their technology readiness levels (TRL) some technologies just don't make it because they do not find a niche market to evolve in and grow.
