The ease of use is great! I can quickly set up an online meeting with my clients from anywhere in our office or across town without having everyone travel there physically which saves time as well money (gas!).
It also has some nice features that we didn't realize when first setting this system such as allowing us easy access via tablet/mobile device so no more needlessly walking over here etc., We have been able using FaceTime calls instead of traditional phone meetings saving both cost & energy usage by not needing multiple people traveling back n forth between offices - just one person at home solving problems remotely vs several out travelling together wasting gas /time..
