You make good points, but it's worth mentioning that Samsung's logo is the word 'SAMSUNG' - it doesn't lend itself well to tattoos at all, even if you were particularly passionate about them.

Windows has a 'picture' logo and occupies the same rung as samsung in the 'quality vs Apple' pie fight, but there are folks out there with winlogo tattoos. I've seen photos of a few different ones, but my guess would be that there's fewer than there would be for Apple.
