PC Forum, Esther Dyson's annual conference is coming up March 12-14 in Carlsbad, California. (Disclosure: PC Forum is part of CNET Networks, which includes ZDNet.) David and I will be attending and covering the event, along with a host of other bloggers/reporters. I chatted with Esther about what to expect at PC Forum [watch the video]. The theme for this year "Erosion of Power: Users in charge." In the video interview, Esther explains how users are gaining more control and vendors are responding to users' demands, and gives a preview of the panels and speaker list. She also talks about the impact of having too much choice and changing attitudes driven by increased transparency.
