I used it once to test with a coworker when we first got it and then twice as we tested it over 3G after jailbreaking (works surprisingly well there). Other than that I've not used it. I'll probably use it a bit more once the kids upgrade (at some point I'm sure) to the new iPod Touch. If a new iPad in early 2011 comes with camera/Facetime then I'll buy one of those for a "family information & planning" device to sit in the kitchen and use Facetime that way as well.
