I have - once opened up the app store to search for things on windows. It was after searching the web - but I barely use windows so the fact that I did at all is pretty remarkable really.

I found things closer to what I was looking for than I did on the web too, but still came to the conclusion that what I was looking for doesn't exist (a good non-mobile app for marking up pdf's with a stylus - the closest I've found is Microsoft Edge of all things).
