You might recall I reviewed some Western Digital kit earlier in the year, specifically their WD TV Live Hub, an NAS and a USB 3.0 portable hard drive. All excellent equipment. They have just upgraded the firmware for the TV hub, which added access to Spotify from this mains-networked device, which could be very useful for users who fancy some music rather than movies. First TV device to get Spotify, as far as I am aware.
Apparently, also coming soon is a Wi-Fi alternative to the TV Hub, which will also include Spotify access, as well as the standard services: Netflix (for US), flickr, Facebook, Youtube etc. If WD send us one of these for review, I will let you know how it pans out.
