I stumbled upon this presentation, shared by Chad Udel, comparing four main mobile OSes. Chad used this for his presentation at mLearnCon 2010. Take a look -

I came across this mind map by Cammy Bean which covers nearly all the tools available for creating/authoring eLearning content. She tries to find answers to three simple questions regarding each tools mentioned in the mind map –

- When do I use it?
- What do I like about it?

After a few years of hype, mobile learning has now started flourishing; the advent of new generation of mobile devices, high-speed network access, powerful mobile browsers and better native apps are all contributing to this. There is still a lack of standardization across devices and amongst networks across geographical areas resulting in mlearning content development being somewhat constrained.

Before beginning to develop mLearning on their own, they should keep in mind some technical considerations. Earlier we’ve mentioned some tools that can assist you in mLearning applications. However, each one needs a fair bit of knowledge and skills before they can actually implement solutions using these tools.
