The extra space is nice. If you know you won’t be near service, or will have spotty service you can download a bunch of movies or seasons. It’s great if you want to have a lot of photos, or plan to shoot a lot of video. 10 or 12 iTunes movies is pretty close to 100gb, still kicking myself for not getting the 512gb as it was only 5 bucks a month more.
Edit:
We go to the country a lot over the weekends, or used to.. anyways we usually have a a phone full of movies and kids shows that we connect with the Apple TV as there is no internet or cell service.
