Education in your hand

What are some of the present and emerging technologies that could allow delivery of education to the hands of learners?

• 3G Cell phones
• PDAs
• Digital audio and video players (iPod and PSP, for example)
• GPS
• Podcasting, blogging, SMS, e-mail
  

Of course, what is really happening is convergence of the above technologies. People are using one or two devices that cover multiple technologies, and the cell phones seem to be the main device for doing this.

The point here is that info can be delivered to people with these devices, and education - first, in bite-sized chunks - is a field that can really benefit. Imagine if you are a Korean business person who is about to have a meeting with your American trade partner. You want to practice your language skills, so you use your phone to log into a service that can deliver expressions with a pronunciation guide, short videos to demonstrate how and when to use the expressions, and so on.

I think I will come back to this topic and develop my thoughts more since I see this as a potential research topic (should I get into a doctoral program).
