While wifi might be limited, the new upgraded mobile phone systems are meeting this need. I just read an article in the Financial Times that the newest technology to be introduced at the International Technology fair is the "smartbook", a combination notebook computer and smart phone. The smartbook will allow access to the internet either through mobile phone technology or wifi with the ability to communicate, access and transmit information, and access/transmit multimedia. In the US, at least, the 3G network is much more developed than Wifi, especially in less populated areas.

The other trend that I see is moving from a central place to hold information to multiple places to record the location of information (delicious, facebook, cell phones) and the communication of where those places can be found (again delicious, facebook, but also twitter).

I think also that there is a battle going on between "legitimate" information and "flawed information". You can read the rest of my predictions here.
