Here are a couple of year old podcasts from Gartner. It's interesting to listen and think about how accurate they are a year on...
The Evolution of Information Access (Jan 3, 2006)
The Importance of Information Access (Jan 17, 2006)
The most interesting thing about analysts is that they claim they can predict the future. In a way this is a bit of a self fulfilling profecy because vendors and customers will change in reaction to their predictions, but they often have very good insight into the markets. Sometimes, things go the opposite direction though.
Have a listen to these and see if you think they are right.
