Do you have Apple products already? (ex. MacBookPro, iMac, iPhone, etc)
If so you can use the Remote application on all of those devices, And for computers you can wirelessly stream your computers desktop to your Apple TV(AirPlay). Theres allot of other features but I am not sure, I will look into more.
If you are into iCloud then thats also a good feature.
