At a recent Web 2.0 presentation, the speaker highlighted the key differences between mobile and traditional Web 2.0 architectures, emphasizing the challenges posed by mobile devices' unreliable connections and high latencies. They proposed a future where mobile devices would preload likely-to-browse content to mitigate these issues, leveraging the decreasing cost of storage and the limitations of current network latency. Audience inquiries centered on conflict detection and management, with Couchbase cited as a solution for tracking conflicts and facilitating application-based resolutions, rather than relying on automatic merge processing, which would require understanding the application's specific merge strategy needs.
