Target market?
Not sure what the target market is for the Machine, as snazzy and well-engineered as it is.
Hardcore PC gamers won't want it because it's significantly underpowered compared to modern rigs.
Console gamers might have wanted it years ago, but there are hardly any good PC exclusives these days, so why would they want one?
For games that need a kb/mouse, either you're playing them at a desk, or, if you already have a sofa setup, probably already have a more powerful rig in the living room or are streaming video from a rig elsewhere.
The pad looks not great, it's difficult to imagine it being superior to the PS5 pad.
