No doubt Microsoft is a money making machine, but regardless of any rankings list I sincerely doubt that their brand is seen as 'better' than the likes of Coca-Cola, Mercedes-Benz, Disney etc.
It would be interesting to see how those rankings were calculated, and whether there were any corporate sponsors who funded it.
EDIT: Didn't Microsoft do exactly that with the original XBox, and leave the Microsoft name off the console and packaging?
