The Digital Signage Expo just wrapped last Thursday in Vegas, and most striking to me was that at this year's Expo, system integrators made more of a showing than in any previous event. The digital signage industry has (too) many events/shows/conferences that feature vendors preaching to the choir, vendors sniffing out other vendors... it was refreshing to see more integrators among the attendees.... I'd like to hear some integrators' thoughts on what they thought of the Expo....
