I love my Chromecast and use it extensively. This is what Miracast should have been, something that "just worked" and seamlessly interconnected devices. But instead Miracast is yet another classic example of "death of committee" where tons of big media and hardware companies wanted to get their features and DRM in, and as a direct result we now have dozens of completely incompatible Miracast devices. I think this tab…
Meanwhile Chromecast is a joke. It doesn't work at work because our employee network requires a username and password and our guest network requires a click through agreement. It doesn't work at the hotels I stay at because again, they have a click through agreement. It works about half the time on personal WiFI APs where the person wasn't security conscience enough to turn on client isolation. The thing is nearly useless for me.
Miracast uses WiFi Direct so works trouble free and lag free. Chromecast is some bizarre crappy second computer that has to connect to the network, but has very little capability to actually connect in the real world.
