This is one of the advertised Kindle Special Offers that I have been looking forward to. I've kicked around the idea of getting a Roku player (and you can get the Roku HD, Roku XD, or Roku XDS) and at this price, I'm going to go ahead and get one. There isn't a channel yet that allows you to play your Amazon Cloud music straight off the Roku, but with the Roku XDS, you can hook up an external hard drive via USB. It's pretty cheap now to buy a one or two terabyte drive, so I can download my music there and play it on my stereo without having to have another computer up an running. We also have Netflix, so can watch movies there and can download Amazon Instant Videos to watch (I find the downloaded versions on my computer much easier to watch than the streaming ones ).
