Sena Case's Collega ($150) is a fancy handbag, adding a large exterior pocket and two retractable hand straps to a zippered iPad sleeve. Straps tucked in, it can be carried under the arm; pulled out, it can be held in the hand. The leather feels nice, and the case is made to suit the tastes of tech-savvy professional women. Sena packages Collega with a cloth carrying bag and sells it in four colors.
