I'll finally be taking the plunge and buying a Mac, my first. I've decided I'll go a with the (relatively) cheap Mac mini (2.53 GHz, 4GB RAM.) I'm cautious, confused, and a little giddy. Anyway, I'll also be buying a 23" 1080p Vizio Razor LED LCD HDTV to use as my display (and a cheap MS keyboard/mouse combo, but that's irrelevant.) If I understand, I only need this and this to get video and audio out of the Vizio Razor (or any HDTV.) Is that right?
