im posting for others thinking of making the change. you cannot airplay mirror xfinity stream to apple tv. no matter what sales says. recently went with xfinity mobile and even purchased an i pad with cellular data from the xfinity, thinking i would still have programing streams during pge power outages (no broadband connection after generator starts) burning cellular data. no worky, nada. the sales pitch is yes, yes, yes. but what you get during pge power outages is the entire family surrounding a 10 inch ipad. i may just stick to antenna stack year round for programing, point one to the north and one to the south. agreement expires, 19mos and counting.
