Input or audio peripherals.

On a good laptop, I would at most need it for audio (cable connectors break too easily when I'm working in a bus/train/airplane, no thanks). But since the devs can't count to three, I'll need an external mouse, and I don't trust that keyboard either. So that's three devices that are best solved with bluetooth, if you don't want connectors to break off inside the laptop at some point.

Mouse, Keyboard, headphones. Dongles work 'fine' - but that's not ideal on a modern device.

I'd expect the company to pick one that works without firmware. I know a bunch of realteks don't need any; Intel has been hopeless for ages.
