For those who were not there (or slept in that morning), ESRI has posted a video slide show from the Developer Summit Plenary on the DevSummit homepage. I thought it was one of the better ESRI Plenary sessions I’ve attended.’ You can use the bookmarks below the video screen to move around (for example skip ahead to the Python or ArcGIS Explorer 900 sections)
