Hey iPad people! New here! I've succumbed to the Apple addiction. Now that I'm here, I would like to know if there is an external hard drive that will not only store my files, videos and pics, but that will allow me to manipulate those items directly from my iPad? I see some suggesting to use your PC for certain things, but I'm not yet comfortable with that option. Just wondering if there is an external hard drive that will do more than just store my content. I hope my question is clear. Thanks!
