I think when series X is in stock it will sell more then series S. Especially in a year or so.But you suggested the X would outsell the S. Once these things are routinely available, casuals will most likely get an S though. Even MS expects that. Which is why I felt you were implying casuals will prefer the more expensive version.
Maybe im wrong and the cheap price make series S sell more.
The fact they are even and there are still Series S in stock makes me think X is more wanted.
Series S selling only 3 million in a year and stock being available doesn’t make me think its doing amazing
