eWeek reports: "Gartner analysts at the Gartner Symposium/ITxpo in Las Vegas discussed what they believe will be the most disruptive technologies through 2012. Disruptive technologies are those that force changes in industry models, business processes, vendor types, products and services, as well as the all-important user model. Take a look at this list and tell us whether you think something has been omitted—or just plain doesn't belong. This list is ranked in order from least disruptive to most disruptive."
Several of these technologies listed in this presentation given by Gartner may sound new and cool, but many of them are older then you think. For example, augmented reality is probably the grand father of these concepts (roughly about 20+ years). Then you have concepts like Ubiquitous Computing, and virtualization (both roughly about 10+ years).
