What's the difference between the Lifesize Icon series and other video conferencing systems?

Lifesize Icon Series is truly Smart Video™, which takes the simplicity of a smartphone and applies it to enterprise video collaboration technology. In the same way that using a smartphone requires no training, Lifesize Icon Series provides the same intuitive, simple experience for individuals with little or no IT experience. Other room-based video conferencing systems are incredibly complex, which can seriously inhibit frequent usage. Lifesize Icon Series is easy enough to use every day for every meeting.
