The compatibility issue is very real. Printer and scanner drivers for multifunction machines are sparse or very basic (to be generous). Essentially, nearly every strange external device could have an issue (3D printer, router, bottle filler, engraving machine, lasers, security dingles, programmable logic controllers, etc.).
And, of course, it you want to play a wide variety of games, it's not the right platform. Putting aside actual compatibility, most DRM runs into trouble.
And for what... More battery life, and very good wake from sleep. Usually (but not always) a cellular option.
I have a Surface Laptop 7, and have bought two ARM Surface Pros of different generations, and they've all ended up being novelties that I appreciate technologically, but cannot use as my main laptop.
