Amazon’s new OS for Fire TV players is a double-edged sword

Here is a 191-word summary of the news article: Amazon is releasing a new 4K streaming stick called the Fire TV Stick 4K Select, which will be its third 4K-capable device in the Fire TV lineup. The 4K Select is a more affordable option, priced at $39.99, by cutting some features like Dolby Vision HDR and Dolby Atmos audio support. However, the 4K Select will run on a new Amazon-developed operating system called Vega OS, which is said to be based on Linux and designed to be more responsive and efficient. This new OS means the 4K Select will only support apps from the Amazon Appstore, preventing users from sideloading non-Amazon apps, a feature popular with some Fire TV users. The 4K Select is launching alongside Amazon's new Omni QLED and 4-Series smart TVs, all of which will utilize the Vega OS. While the new streaming stick offers 4K capabilities at a lower price, the restricted app ecosystem may disappoint those who rely on sideloading apps on their Fire TV devices.
