I use this with a Goflex Homeserver and have been impressed. So far no glitches and is as fast as the server will allow. Video, audio, documents, photos all stream to iPad faultlessly. Only limitation is what the iPad can handle, ie. it streams data but does no conversion so no AVI’s only MP4. Not a problem for me so 5 stars.
