I use it, I am required to use Windows, and it’s a huge improvement over doing Data Science on native Windows, but the terrible filesystem access ruins what otherwise would be a seamless experience.

It’s fine for running small models but when you get to large training sets that don’t fit in RAM it becomes miserable.

There is a line where the convenience of training or developing locally gives way to a larger on demand cloud VM, but on WSL the line is much closer.
