Hi , i agree with a1exh,
The price review is comparing storage prices from Nas devices and direct attached storage but does not compare the price of this NAS with other NAS !
The Mybook World WhiteLight is one of the cheapest NAS, can stream media over dlna, have correct performance when wired. ( it will probably go thru CPL instead of wifi when streaming to your console...)
Additionnally, you can even add more features to your Mybook if you want to apply some modifications (voiding your warranty) described on some sites.
