I have a question. I know how I can use my iMac as a tv. I'm thinking about getting rid of my tv and replace it with the imac. I want to be able to sit on my couch and watch tv on it, but also use it while sitting behind my desk. When it is placed on the desk it is to high to watch tv on it in a relaxed way. Does anybody has a setup with a swivel arm? Or are there any other ideas. Please let me know if you have any ideas.
