This isn't as much of a problem if you use Chromecast with a tablet. Also, you can actually connect multiple devices with a Chromecast. I think it's better to think of Chromecast as a wireless display device for your {smartphone,tablet,browser} than a displayless smart-TV. It's just a tool to turn your TV into a dumb client for your smart device of choice. If you want something that extends your TV rather than something that lets you use your TV to extend other devices, you're better off with an Amazon Fire box or equivalent.
