Real Men Use Android: Special Forces Favor Google Phone | Danger Room | Wired.com
One issue I grappled with in my novel Phase Line Escher was the future of portable computing--both in daily life and in combat. In the book's time frame it's entirely possible that an individual's personal data processing needs could be met by microscopic processors, so my primary consideration was display size and convenience of transport.
Essentially something with a large enough screen and useful graphic interface.
My choices for the civilian environment were tablets and pads as well as slates for people who favored larger displays. For the military, net phones to suggest the primary function of a communications device for text, voice, and graphics.
Looks like that was a good choice.
