Still use my ZuneHD-64, and even my Zune-120. I recently deleted all of my "subscription" music though, in preparation for the inevitable demise of the service. Microsoft has been slowly picking the Zune Marketplace apart, and I don't think it will be around much longer. I suspect that the Zunes will never be able to sync from XBox Music either, so might as well clean house now.
I purchased a Surface, and set it up with my "Live" account, and set up XBox Music. Some of my Zune subscriptions showed up immediately for streaming, but not all have. I suspect there was some cut-off date.
