4 Smartphones for Mobile Pros
Samsung Galaxy S4
There's some serious hype surrounding this successor to the Galaxy SIII, and for good reason. This Android model offers nifty consumer-oriented tricks like using both cameras (front and rear) at the same time and a sensor that can read gestures. But it's also outfitted with high-end business features. For starters, the KNOX service keeps business and personal apps split between two distinct views. You can also encrypt the phone to protect files. And here's a unique feature: One version of the S4 will have an octa-core (eight) processor running at 1.6GHz for blazing speed.
