http://store.apple.com/us/product/MC953ZM/A I have a 4th gen Touch, and the Retina display is 960x640. I understand this adapter only supports full mirroring with the iPad2, however it's not clear what kind of quality I'll get from my Touch. The site says "up to 720p" for models including iPad2, which doesn't answer my question. Anybody tried it? How's the quality? Worth the $40? I have Digital Copy movies from Blu-Ray's I've bought, and they're 853x354 or 853x480. Presumably that's what is output to the TV?
