Logitech Orbit AF, by the tv on the stem attachment; matches perfectly the video eye level on the 50 inch tv. Has perfect angle to cover the room on minimum zoom, or zoom on the couch only, or pan around the room onto the kids showing their tricks to the grandparents. 4x2.5GHz phenom is powerful enough to encode the video; but as my bottleneck is the upload speed, it probably never had to encode HD. Microphone does not get any complaints.
The greatest problem for me is the pan and zoom control, I have not found a way besides clicking with the mouse on a panel on the screen (using the remote would be perfect, but I have no time to play with 3rd party remote control applications).
