Has anyone used this? It is a cable made for the iPad which not only has the yellow/red/white A/V cables but also the red/green/blue component cables, supporting sound each way. I'm interested in seeing if this is worth having mroe than the VGA adapter and a VGA cable. The pricing between the two options is similar. I need a good cable that will not only allow me to hook up to projectors for my presentations but also to my HDTV with component-in for other stuff. I'm fully aware that video or image -out is app-specific.
