This doesn't seem much different from the MediaLink HD that HTC has had for over a year now. Although that ran Android and this runs Chrome. Both were capable of talking to NetFlix and other content URLs directly once they got the WiFi information from your device. This helps devices save battery since they don't have to download the data just to resend it, and don't have to transcode anything. That said the MediaLink HD often had lag issues that kept it more in the realm of presentations and media and made it difficult for real time games. Even for presentations I'd often carry my own WiFi AP around with me or find ways to get it just to connect between the phone and device to avoid them. Home performance is probably better than conference and event performance. I recently tried a Netgear Miracast adapter to send HDMI from an HTC One and the lag is completely gone. I haven't tried Google's implementation of Chromecast yet, but I'm suspicious it won't be nearly as lag and trouble free as a WiFi Direct only device like the Netgear, though. You have a whole extra OS running device in the chain to make things a pain. So I'm suspicious the extra complexity isn't worth it for this class of devices.
