It seems like casting from a tab uses more resources, uses double the bandwidth, and has limited features compared to just dual-monitoring.
In order to continue using a VPN and chromecast I have to mod the firmware on the router. chromecast uses a fair amount of resources when casting video. And as far as I can tell there's no benefit (besides it being wireless) compared to HDMI out dual monitoring... am I missing something or is it really just nothing that special?
Casting from a tab (or the entire desktop) is not Chromecast's core use case. If that's all you're doing, then you are
better off using HDMI or WiDi.
Chromecast's advantage, in addition to the sheer browsing/usage/convenience factor that @Kyonz
mentioned, is "offloading" the playback duties. Chromecast's power usage is far less than your laptop, and you're free to take your laptop/phone/tablet and run if you need to while Chromecast continues to play. Someone else in the household can easily take over control of Chromecast from another device as well (there's some annoyance/bad to this too, but it's good as long as everyone plays nicely).
Likewise, I can move where media is being played back in most apps by pausing the playback, and resuming it on another Chromecast. Sadly, it won't turn off the TV though.
The previous paragraph deals solely with Chromecast-native applications, ie, not tab-casting or desktop-casting with the Cast extension from Chrome. Like I said in the beginning, if you're mainly trying to cast your computer's tab or screen, Chromecast is not
the ideal solution.
