I have the 16Gbyte RAM version, so it is working nicely for development. However it is setup for development under Linux not under Windows. So when i target Windows i typically cross-compile. I do have a native Windows debugger on the machine itself but again i typically using remote debug via Visual Studio.Couldn't you build Dolphin/Qt natively on your WoA machine? Lack of tools? Lack of memory? Not powerful enough?
For my purposes WSL2 is totally sufficient as far as Linux is concerned. I guess it depends on what you are planning to do under Linux. It is for instance not ideal for gaming since it lacks a native GPU driver.As far as I am concerned this little sentence in the Dolphin blog entry is enough to disqualify the device at the moment:
I don't care about Windows, I want to run Linux natively on the machine.
I wonder if Samsung Book S will be better (though it seems limited to 8 GB RAM / 256 GB SSD which is too small for me).
