Umm… How old is this meme? You haven’t (really) able to play PC/Steam games on Mac for a while… Also, XFCE hasn’t been a serious contender for a DE (save for a lower end hardware spec) for quite a while now.
This meme might have made more sense if it was comparing to Windows. Comparing it to a Mac now is comical, especially since a lot of Adobe software doesn’t work quite right yet on M* series Mac’s yet (though it is better than at launch).
Well, their username does check out.
