Apple Thoughts: Is FaceTime Something You Find Useful?

"Apple is expected to add a front facing camera to iPad 2, bringing yet another device into its "FaceTime" fold."

And the question came up about it's usefulness, or lack thereof. It got me thinking, how often do I really use that feature? The front camera is nice, and I use it a lot, but mainly for taking pictures when I'm with someone and want to be in the picture. I have used FaceTime with my daughter, but mainly as a remote viewing device so I can help her solve some problem on the computer, with her homework or with the XBox 360. So, how often do you use FaceTime and how do you use it?
