I've been looking at the Apple digital A/V adapter for quite some time and I'm debating whether I should get it or not. I really like how it looks but I don't know how I would use it besides playing Real Racing 2 and other games, watching YouTube videos, and Skyping. I can't imagine other uses for it since I already have Netflix on my HDTV and I don't do many presentations. Do you think I should buy it? Is it worth $39? How else could I use it?
