The N900 from a Community Perspective

''I noticed that the N900 has the well known S60 video streaming app, “Qik,” available in the repositories, but I didn't have a chance to try it out. I think we might see some very interesting video streaming apps become available in the future. Perhaps news reporters will stream video live from their N900s as events happen?''
