A few months ago my wife started using my old iPad 2 more and more. Pretty soon it was all she was using and the kids were using her MacBook. For Christmas I got her a new iPad 4 and she was thrilled.
She mainly uses the web and email, with some rare Excel and Word document reviewing with iWork. For light photo touch up iPhoto has been fine too.
They are soldiers! As far as I know the "warfighters" term came around during the 2nd Bush presidency, but I may be wrong.
I remember doing some work in the Pentagon at the time and everywhere there were signs about "warfighters". It's an asinine political terminology created to make everyone feel included when discussing the military. It would be like calling a programmer a "keyboardtyper".
