And yes, it would use your mobile data..... I doubt it would work for me anyway because my mobile connection is laughable at home. I will have to measure whether the Chromecast uses data when I'm casting a DVD from the laptop. I don't think it does, I think it's just using the wifi as a conduit, but I'll check. It uses data through Backdrop for sure unless tamed as mentioned before, those images are being refreshed every 30 seconds. Also from what I've observed, it can use 30-40 MB when first turned on just syncing up, checking for updates, and lord knows what else.
