Amazon has introduced the new Fire TV Stick 4K, which operates on Vega OS instead of Android. It is available for purchase at .99, with a promotional price of .99 during Prime Day events. The new model offers a 20-40% performance boost over competitors and has a more compact design. It can draw power directly from a TV's USB port, simplifying setup. The redesigned remote features an asymmetric shape, a metal home button, a customizable Star button, and infrared controls for managing other devices. The transition to Vega OS includes over 2,000 new apps added this year, but it no longer supports sideloading. The Fire TV Stick 4K is now available in the United States.
