Also like the Wii, Apple says it will be possible to play some games with a standard controller as well (though unlike the Wii, these controller can only be acquired from third-party manufacturers). While the ability to play games with standard controls is very welcome (especially considering how significantly the Wii motion controls eventually declined in popularity), the fact that the controllers will be sold separately (and not even by Apple) leaves open to question just how widespread compatibility will be.
As disgracefully late as it may be, it is nice to finally see Apple take the inevitable crack at the TV gaming system market. Let's hope that they can catch up quickly and actually try to come up with some innovations of their own for that space. The new Apple tv will become available sometime next month.
