One Drive works perfectly. I've used it to store game saves, photos, videos. Anything works. The only advantage MS Office compatible files have is that they can be edited online in an online session of word, excel or PowerPoint.

It's still a disk integration like DropBox. That aspect works pretty well. So yeah, for me, it's like similar pricing as the others but, hey office on Mac or PC on 5 computers (family plan for me).
