I did this retreat and found it to be extremely valuable (http://www.curiousjuice.com/blog-0/bid/141396/Vipassana-10-d...).

However, its value only carries if you continue meditating daily, at least for 30min, which I haven't done and I suspect most of us will struggle to do after the retreat.

I agree with the last point that most tech is aimed to get your attention and few things are actually worth it. I'm working on a model for news/media that addresses this shortcoming.
