How often do you make video calls from your iPhone/iPod Touch?

Skype has released evening video call/video chat service for iDevices a service that allows all Skype users to initiate calls between iDevices or between iDevices and computers. I noticed a lot of people ecstatic that this option finally exists on Skype more than half a year after the launch of the iPhone 4, the first iPhone with a front camera. I can't say that I'm particularly excited about this new application because to be honest I don't make video calls that often, the only ones I made were via FaceTime/Yahoo Messenger and Wi-Fi.

Skype is not the first service to bring video calls to iDevices because we have had the opportunity to do so since the fall using the Yahoo Messenger application. Of course, Skype is for most Americans the easiest way to communicate with friends, and that's why Yahoo Messenger didn't get the same promotion when it launched the video call service. However, let's not forget that Yahoo Messenger was the first service that allowed video calls and Skype simply followed with the same implementation.

Returning to the topic, how often do you make video calls using your terminals? And here I mean video calls using any application that allows this and of course regardless of the 3G/Wi-Fi connection?
