Google just announced a souped-up Chromecast
The new "Chromecast Ultra" comes with support for 4K resolution video, HDR, and Dolby Vision, and costs $69 - an additional $35 over the regular Chromecast that streams in 1080p.
In late September, Chromecast's main competitor Roku announced its new lineup of media streaming devices. There are now five new Roku streaming boxes to chose from with varying features, one of which has been dubbed a "Chromecast killer." The new $30 Roku Express has similar features as Google's Chromecast, like 1080p streaming and app support, for $5 less.
