What I'm referring to is not a specific application but the new wave of fun to use, immersive, and interactive applications like "MLB.com At Bat". I'm not a big baseball fan, but MLB.com At Bat is worth a look to see how much interactivity can be crammed into an application without the app feeling cluttered, confusing, or sluggish. I think the "killer app" will be the future apps, like this, that allow you to become immersed in the content (TV show, sporting event, game, etc) and provide a fun and unprecedented level of interactivity. Look at what MLB.com At Bat offers: - Live audio stream (able to play in background via Safari) - Live video stream - In-game highlights - Interactive elements (follow pitch) - Overlay of up to the minute scores and stats - Configurable push notifications - Linked access to more in-depth info (news, schedules, rosters, background info) - Searchable video archives - Imagine if they added to that a social networking component (facebook, twitter, buzz, etc) The iPad and its larger display will spark even more innovation in the app space. ** No, I am not affiliated with or attempting to promote MLB.com At Bat. It was just the best example I've seen of what I see as a new wave of apps that will make the tablet/pad experience very, very enjoyable.
