The best thing about the Oculus Quest 2 is being able to play games untethered, flailing about in Beat Saber without worrying about tripping over the cable or yanking it out of your PC. That only works natively for games installed on the headset, however, and if you want to play PC VR games like Half-Life: Alyx you need to either plug in a USB cable, or fork out $20 for a third-party solution like Virtual Desktop.
