Like! Making it so easy to share & interact is a huge advantage.
What I like most is the fact that I don't have to think about...
1. what I want to share: text, images, documents or my desktop
2. how I communicate: via text, voice or video,
3. where I am: desk@office, meeting room+video endpoint or at a hotel.
4. which device: a browser, native application or my mobile/tablet

It's available when I need it, allowing me to focus on WHAT I want to accomplish, not HOW.. And for some reason that's quite important to businesses ;-)
