This will probably be the biggest competition the Steam Deck has within the handheld PC space.
Most noteworthy is that windows is finally focusing on providing a decent handheld experience, including booting straight to a controller friendly interface, and reducing background processes for better fps and battery.
It’s not clear if the improved handheld focused version of windows will be available to other handheld PCs or not.
It’s also the ugliest handheld PC yet (imo), but I can appreciate that they’re pushing for comfort over looks.
They also seem to be pivoting towards trying to make “Xbox PC” something to replace Steam (see the end of the Super Meat Boy 3d trailer).
I wouldn’t be surprised if they try and lock out developers from putting games on Steam and being exclusive to “Xbox PC”.
Worked so well for Xbox Live for Windows…
…and this risk is exactly the reason we got SteamOS, Deck and Proton.
