I have Apple TV and i stream the content from my computer. Was ok , but is getting slow and slow.. take sometime to load movies, when i foward takes more time.. after i did the upgrade to my imac c2d support N became slow ( i dont thin is because of that ) so upgrading from airportextreme to the new airport base will make this disspear ? i mean will be faster the streaming ? and one more question i would like to conect to airport my external HD , thats only possible with the new airport right ? i want to be able to play content from my HD on apple tv, dont know if thats possible.
