Query: it's a friggin' USB Extension Cable!!!

How can they even call it a dock connector? It's just a mere usb extension cable, nothing more. u know what? just go and buy urself a USB hub for like $20, and u'll get not only the supposed dock connector, but also, u'll get a few more ports. They need to reduce the price of this thing, no way does this merit $30. If they had at least added a line out and made it a two headed usb cable, then, it might be worth it.
