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.
Edit: The handheld Xbox UI will.come to all windows PCs, but it’s not clear if the reduced performance bloat version will be available. It sounds like only Xbox branded devices may get the full benefit of optimized windows.
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.
It is hilarious to see Microsoft put so much effort into proving to bystanders that what Valve did was necessary for the industry.
