I had an interesting chat with Pat Mahon from Carlow in Ireland about how he uses his Mac. He has a MacBookPro and a MacMini. We go through the 20 questions and talk about loads of stuff along the way.

I use ScreenFlow to capture video from my Macs and also VideoCue, both from telestream. ScreenFlow has video editing capabilities that make it a worthy purchase. You can do lower thirds and titling really easy. I like the way I can easily zoom into an area of the captured video to highlight something with a video action. I can even highlight mouse clicks. I sometimes record myself with the iSight camera at the same time with ScreenFlow, sometimes with the computer audio as a separate track from the microphone audio. Good for doing narration over clips recorded.
