Who's for widgets?

I recently saw an article in Brand Republic that may raise some interesting debate.
The article discussed how widgets may replace email as a marketing tool in 5 years time and are going to be for online marketing what SMS was for mobile - a disruptive technology that will change the way we do things.
The case was made around the fact that email is about telling and that showing is a more powerful form of expression. The smarter the widgets, the more we could do with them. If widgets were put on a mobile phone, the story widens and the audience becomes more broad. They won't be just useful to teenagers anymore but will be used by almost everyone.
It would be great to know other people's thoughts regarding this?
