Connect with multiple people simultaneously: With group video chat and web conferencing you can connect with multiple people around the world at the same time.
Share your screen: Ever look at something that you couldn’t quite put into words? Well, with screen sharing you give other people the ability to view what’s on your computer screen. You can choose an open window screen on your computer and give everyone in your meeting the ability to look at it. Learn More

For enterprises- you can throw out your video conferencing software and collaboration tools and get a new mobile app for free.
Small drawbacks in the Google Plus-
lack of integration with Youtube (it is one way integration from youtube to hangouts but not the other way round fixed ), lack of a whiteboard for sketches- (like again a shortcut to a google doc :) ) or even bundling the record from your web cam to record your desktop.
Ultimately enterprises want to know how they can use this stuff for e-learning modules or webcasts.
Check out NY Met Museum with Friends (thanks to Google Art Project)
Play Linkin Park Playlist (100 videos) with Friends btw. great graphic redesign of Youtube icons!! Now if we could only convince the Google Docs to get more integrated with Open Office or LibreOffice templates
or even set up a DJ table session using Google Hangouts. with Extras of course.
But as it stands it may be good to go for webcasts !!
