Dan Gillmor has a good column in the San Jose Mercury News on camera-equipped mobile phones. Seems that:
1. In countries where the medium has found a market, users are communicating in new ways, revolutionizing everything from journalism to political protest.
2. Meanwhile, companies investing in the phones seem to think they'll mostly be used as "a 21st century vehicle for content delivery, much like television, or an e-commerce tool. If we can view videos on our phones, they reason, we'll watch what big companies deliver. If retailers can tell us about items on sale as we pass by their stores, we'll buy."
