This new handheld OS is a huge threat to Valve and the Steam Deck

Windows is closing the gap to SteamOS and the Steam Deck in general with the new gaming-focused approach to the Asus Xbox Ally handhelds. This new, stripped-back version of Windows boots directly into an Xbox full-screen experience and gives little reason to ever leave the application.

While the Steam Deck is still the best gaming handheld for most, the recent reveal of the Asus Xbox Ally is the biggest threat to Valve's dominance. It's unsurprising to anyone who has used both a Deck and a Windows handheld that the key to Valve's success has been software-related, more so than hardware.
