There are plenty of supposed Steam Deck killers available in the portable gaming space, from the Asus ROG Ally to the Lenovo Legion Go and all the Ayaneo and ONEXPLAYER devices in between. But none of them have managed to outright slay the dragon that is the mighty Steam Deck yet.
This is “the point” from the article, which is that we expect a portable handheld to provide an experience like a console portable handheld would, rather than a PC in a small form factor. My two cents is that I’ve found the Steam Deck’s “sleep” function to be very much like a console’s, and it’s not something that Windows does very well.
