Microsoft is set to revolutionize the handheld PC gaming market with its upcoming full-screen Xbox UI for Windows PCs, launching in 2024. This bold move positions Windows as a formidable competitor to dedicated handheld consoles like the Steam Deck, offering a seamless Xbox experience on portable devices.
