Trends in the Mobile Gaming Industry and Serious Games

In Mashable:  These trends are mostly about mobile gaming for entertainment, but I watch these trends for their potential applications beyond the 'angry avians' places.    I am struck by the increasing ability to do serious things in contexts like tablets, where there will be enough real estate to clearly mark out say a process that has real choices in a corporate decision making palette.  That for internally facing games.   Or for mapping  consumer choices,  in externally facing games.   Smart phones are just too small to provide more than trivial choices-spaces.  Making a decision process into a game requires that the designer differentiate the choices.  That was made clear to me as I started to explore the use of mobile devices for mind-mapping.  Looking further on that now.   Thoughts?
