There are plenty of Windows on ARM laptiops available from major manufacturers, including Microsoft, Samsung, Acer, Asus, Dell, etc. Microsoft notably sells their ARM laptops for less than the Intel version; not sure about the other brands.

The iGPUs obviously don't compare to dedicated GPUs, even those that are a few generations old, but it has enough power for gaming in lighter games and even heavier games if you're willing to turn the graphics to low and lower the resolution.

Last I saw, there were a lot of game incompatibility issues, but I haven't been paying attention since launch. But this thread is literally about Epic improving their support on ARM, albeit with a "they hate Linux!" spin on it.
