That's an awful lot of words describing a device which is still worse than the Steam Deck as a portable gaming tool purely by virtue of running Windows. I feel like all of these companies trying to cash in on the Steam Deck's success just don't understand what makes a portable gaming device useful to the majority of players...
The article doesn't specifically say it runs Windows, but it claims it's an upgrade to the GPD Win 4, which runs Windows, so I think we can assume.
