New service of iTunes Download

Wow, it’s cool! From this week iTunes music store started new service. We can watch some Music Video & Movie trailer with iTunes. Though it might be not supposed to save these video files, we can watch these as many times as possible by free.
I think this is the first service to download some commercial video files officially and legally. I am looking forward to what is the next service of iTunes.
Tonight I will enjoy these video files!
