iRobot Ava 500

The way we do business is evolving, letting you work effectively from your bedroom or home office. As a result, notions of business casual have changed, morphing from polos and khakis to tighty whiteys and slippers. The iRobot Ava 500 ($2,500 a month) is part of that change, making it possible to work from anywhere and still be seen in the office — just make sure you're decent from the waist up. A collaboration between iRobot and Cisco, it features a rolling base with a 21-inch HD screen, video camera, and WiFi connectivity (so your colleagues can see you and you can see them). You control it from anywhere using an iPad, enabling you to catch up with coworkers at the water cooler or attend a board meeting, all without leaving your apartment, or putting on pants.
