Xander, you said "...many organizations simply don’t have the expertise to deploy, manage, and scale client virtualization..."

Choose a thoughtfully designed platform and you won't need specialized expertise. I've been using the Google Apps service on a Chromebook, Nexus tablet and Android smartphone. The Google suite is a very capable offering, and works flawlessly and securely across all mobile devices.

Also, unlike many of "enterprise-grade" collaboration tools that promise to develop useful functionality, Google Hangouts is a full-featured free service that does everything you would expect, today.
