I just set up a personal cloud at home (the WD My Cloud NAS drive). My old Surface RT recognized it immediately and I easily mapped the public and private shares for easy access. Works like a charm. My kids' iPads? Not so easy. The best solution we could find was to PURCHASE an app (FileBrowser) which, after much time and effort, seems to work. Also, only a small portion of the video library on my NAS drive can be played by the iPad (the mp4's). So sad. Yet another reason they should have bought Surface's.
