When the Apple TV gets apps I think we will start to see the beginning of the end for Nintendo... thats the iPod for on the move and the Apple TV for the home casual gaming..
You can buy a wii game for £40 or almost 80 59p silly games on the Apple tv... and using iphones / ipod touches as an additional controller...
But you still need a device to stream it to... I've been looking for a way of running our conference using apple tv's I'd love to be able to send all the keynote presentations to the apple tv without having to have a device to stream them..
