My 2c.
I have owned the WDTV and last year switched to the Amazon Fire TV.
Without a doubt if you can, get an amazon fire tv, the user experience blows every other streaming device out the water. Since it runs android, you can set your own dns service and so watch netflix, hulu, hbo, amazon instant video easily. And that bluetooth remote, oh my, I don't have words, it's almost like, why aren't all remote controls bluetooth??! You can now hide the gadget behind the tv since a clear line of sight isn't necessary anymore.
In the US it's around $99, on e-bay slightly less. Not seen it anywhere locally though. :(
