I got a 128gb iPhone 6+ because I was tired of counting my space with my previous 2 16GB iPhones. I am only using 5.6GB of my iPhone 6+'s 128GB space (108GB free). I'm planning on keeping my 6+ for a few years, if I can - and I don't plan on deleting photos every time they hit a few GB like I did on my 16GB iPhones -- and I plan on installing a few more apps that I otherwise wouldn't, to save space. But to store anything specifically? Not planning on it. All my 30+GB of music is in the cloud. My gigs of pictures are in the cloud ---- but having the freedom of space is nice (2 weeks of owning the 6+ and I'm very happy).
 
Music, TV, movies, pictures, video clips, apps.

I cache YouTube videos for later viewing, so that also takes up a bunch of space
 
Music, TV shows and movies, apps, photos, games, comics.

I was so pleased when they announced that the 6/6 plus would come in 128GB.
