I'm buying a new webcam today. I can't decide between the Logitech c920 and the Logitech c930e. Its appears they are very close but these are the differences i've heard: c930 has a wider camera angle making it so you can see all of the room. It has the ability to tilt and be moved left and right w/o moving the stand. But you lose HD when you zoom in and out inlike 920. It also does not have the software perks like the c920 (being able to put scrolls or animation on the camera screen) Any thoughts from someone who has used both?
