Sony would probably respond that the button technically isn't even pronounced 'ecks' like the letter, but is in fact the 'cross' button – they are shapes, after all. This line of thinking hurts our heads.
Spencer is, of course, just messing around – but it's a pretty amusing clip. What's particularly crazy is that all three major platform holders – Sony, Nintendo, and Microsoft – all place their buttons in different locations. We imagine that could get quite confusing for casual players who aren't intimately familiar with the layout of each controller.
