True, user error is always a factor -- no matter if the technology is a mobile phone, television set, or coffee maker. But paid or free, some services are easier to use than others. The features vary as does the quality of the experience. If it's my business, I'm going with a proven, reliable provider that delivers a consistent experience.

And WebEx is free to meet and work with up to three people. So, yes, sometime free is right on the money.
