As far as having things in different colors go, they are. They were the ones who first invented the practice. I remember years ago when they came out with the old original Gameboys in different colors and I remember that was a big deal at the time because it was unprecedented. You didn't see other systems before that offer multiple color options, so Nintendo invented the concept.
Now as far as what I said about Microsoft being uncool, I would refer you to the Zune. That was MS's attempt to counter the popularity of the iPod and it was a total failure. I don't think anyone thinks Microsoft is a cool company. They've found success with the Xbox, and it is a very popular console, but that's not so much because of it being "cool", but rather because Microsoft used its wealth to force people to like it. Microsoft is like some spoiled rich kid with no friends, so they have to pay people to pretend to like them. That's why you see all these money hats from Microsoft for exclusives and timed exclusives and all that. That's the only reason anyone likes them. Its not becasue they are "cool". Without that money propping it up the Xbox brand would quickly collapse.
Maybe not everyone likes Nintendo, but those who do like Nintendo do so because of what they are and not because of money hats. Nintendo doesn't pay for its love like Microsoft does.
