Hey thanks smiller,
I never got to test it yesterday as the weather was bad and it's not looking great today but soon as i get a chance im going to try it all out. I totally get what you mean about either having the goggles or the tablet due to the one usb connection, if the head tracking was to work then i think i would have a good enough reason to keep them but if it doesn't and only live view is useable, then i would probably return them as i think its not worth the cash just for live view. Hopefully i get a chance today to give it a go!
