joystiq answers a darned good question:
Good question: why doesn’t the Xbox 360 have its own browser?
We don’t want a complicated solution that requires an operating system (though, at any given time, we’ve got all kinds of computers on around the house). We just want to turn on the dang console and be able to browse Youtube every once in a while, maybe between sips of mind-slurrying substances. It’d be neat.
Now where is it?
Check out some of the comments on this joystiq post. There are a few intelligent observations mixed in with the usual fanboy idiocy.
