When I purchase a movie, how can I just watch it via iCloud, I've deleted several of the movie files to save space on my hard drive and now cannot watch the movies on my Macbook, while I can stream them from iCloud on my Apple TV, iPhone and iPad. If I must keep the files, can anyone recommend a good wireless external hard drive where they'll always be accessible? Would you recommend an AirPort Time Capsule for this? Are there any good non-apple wireless external hard drives you'd recommend?
