Hi, Lewis - useful post.

I have nothing particularly to add to your comprehensive discussion, but I did especially enjoy your reminder that all our glitzy productivity tools "will only ever be as effective as the individuals that interact with them".   We so often emphasize the technology over the users and you have rightly reminded us that the person's skills are key, not the capacity of the software, application, or gadget.

I also think that your revisioning productive work as something to be valued and protected is a strong point.   The example of keeping folks out of meetings so they can concentrate on their important tasks is pure gold:).
