Xbox 360 controllers (and their knock-offs) are still extremely common choices for PC gamers who want a controller. Xbox because they have good windows plug-and-play, 360 because there are still plenty of $20-ish dollar ones available, as opposed to the ~$40-50 range for the Xbox One controllers.

Wired Xbox 360 controllers (and most of their off brand alternatives) have a non-removable USB-A cable.

There's plenty of cheap adapters for these use cases.

		It's not "these use cases". It's the primary use case for the USB ports on this device. The entire pitch for the Steam Machine is to use it as a gaming console. Needing adapters for the most common controllers would be nuts. There's plenty of C-to-A adapters for other use cases.

Series X controllers are easily worth that extra $20-$30 for the jump in quality.
