Lovely post today on Talking Points about what to do if people are paying more attention to their Blackberry/iPhone/Pre/etc than you.
My two favorite quotes from the post:
I have a simple solution for this problem. Be better than the Blackberry.
And the most important:
The Blackberry is a technological breakthrough that allows people to do something productive during meaningless meetings.
So in other words - if people are constantly are on their smart-phones than listening to your meeting - maybe the problem isn't them but the meeting (or presentation) itself.
