I just presented the first segment of the opening keynote at Adobe Developer Tech Day in Shanghai, China. Fellow evangelist Enrique Duvos is now on the stage wowing the audience with Stage 3D demos. This is a very technical audience, almost all online all the time. The interesting thing is that standing on stage I counted exactly 5 open laptops, everyone else was online on phones (primarily a mix of iPhones and Android devices) and tablets (iPads). My key message was on the importance of building apps for multiple devices and platforms and form-factors, and not being locked into single-vendor development which will preclude you from reaching a broader market. The audience themselves validated my point better than I could do so myself.
