It is interesting that while definitely the "Wii" and "Nintendo" brands are both better known than xbox, but apparently, the latter replaced "playstation" as the "generic game console".
It's an especially good example, that apparently, Obama is more familiar with the Wii, yet he chose the xbox as an example for the stereotype of stupid video game nerd kids not studying enough. Probably the "Wii" name didn't become generalized, because there is only one "Wii", while there are two "xbox" consoles, the PS3, and the 360. (in the meaning as he used it).
When people say "I will play with my Wii", they actually mean it, because its content, interface, target audience, and pourpose are that different from the other two consoles, while most laymen don't care about carefully specifying if they played the very same TPS on a PS3 or on an x360, because for them, they do the same thing. Maybe if there will be another "casual" console, both of them would be called "Wiis", while the nerdy consoles would be "xboxes" or "playstations", depending on the temporary leader of the genre.
This might mean trouble for them, since trademarks can't be too generic, any word that is synonymous with "video game console", is banned from being the brand o a video game console.
