How about Windows running on M Series Macs? That would probably be one of the best Windows machines on the market. Risc-V while a noble idea will initially lead to some really junk laptops just like the wave of Chinese ARM "laptops" from a few years back and more recently the junk from Qualcomm. Eventually I image the experience will get decent but there will be nothing but disposable junk for a few years until the ecosystem and performance become something consumers can use.
