Let's start with the basics. Wikipedia says that mobile learning is distinct "in its focus on learning across contexts and learning with mobile devices," and then quotes definition of mobile learning from mobilearn: "Any sort of learning that happens when the learner is not at a fixed, predetermined location, or learning that happens when the learner takes advantage of the learning opportunities offered by mobile technologies."
I think that where we learn is only one side of the equation. The second, no least important, side is where and how do we create materials used in learning. Creating flash cartoons or using Captivate might work (and does work) well in many cases. It is probably not be the best way to document a real-life process. Take, for eaxmple a task as simple as clearing a paper jam in a copier. Suppose you need to create a lesson teaching users how perform this task. Now, let's say that you don't have a copier (or that particular model) in your office. It's somewhere "in the field," but you still need to create this lesson asap. And it should be good. You probably think about a team of video and audio techs you need to assemble, about scheduling editing time and so on. How about you grab your phone and get out of the door, get to wherever that piece of equipment is located and document all the necessary steps employee would need to take to fix the problem. Take a picture, add text, add another picture or shoot a video, add more text ... Create step-by-step guide right on your phone, edit it, upload to the cloud (or to your company's server), share, publish to your knowledge base, web site, FAQ section or e-learning module, use it as information exchange module with clients or students, enhance your tech support, publish to your facebook page. You can do it today with AHG Cloud Note.
At the same time, using AHG Cloud Note we are getting closer to informal or semi-informal, peer-to-peer learning, where immediate help is as close, as your smartphone. The good news is that these informal training sessions do not disappear. They continue life in your searchable knowledge base, FAQ section, or tech support section of your web site or intranet.
