Samsung's army of Android phones just got a new recruit with the Galaxy S4 Mini, a watered-down version of its bigger, badder brother. The mid-range Mini doesn't depart from Samsung's tradition of milking its flagships with variations on the same theme--but that doesn't mean the S4 Mini is not a capable phone.

Cisco CIO Rebecca Jacoby spoke with IDG News Service on the sidelines of the NetWork conference last week and shared some insights into the legendary enterprise IT company's own enterprise IT.

One smartphone doesn't fit all, and the choice really comes down to what you're looking for in a handset.
