Now it's at it again, but this time it's trying to convince select Fire Stick users to buy a brand-new device. If you have an older Fire TV Stick, getting the Fire TV Stick 4K Plus for just $15 is an incredible value. More importantly, the Fire TV Stick 4K Plus still runs Fire OS, the Android-based operating system Amazon has used on its Fire TV devices for well over a decade. That's in contrast to the newer Fire TV Stick 4K Select, Amazon's latest entry-level 4K streaming stick, which runs Vega OS, the company's new Linux-based operating system that doesn't support sideloading. Fire TV, Roku, and Google TV are all guilty of throwing plenty of them your way.
