With the last-generation Chromecast, Google managed to turn its inexpensive streaming device into something that was fast and genuinely useful. Now, as the rumors foretold, there's a 4K/HDR upgrade: the Chromecast Ultra. It's still a svelte puck like the earlier models, but it has a bit of a stealth bomber aesthetic. And at $69, it's far more expensive than the current $35 Chromecast. Still, it comes in $10 less than Roku's cheapest 4K player, and will be useful for anyone who wants to quickly stream high-res video to their new 4K TV.
