Sony's original "Netbox," the SMP-N100, was always overshadowed by more popular competitors like the Apple TV and Roku XDS. That wasn't entirely fair, as the SMP-N100 was loaded with streaming media services (Netflix, Hulu Plus, Amazon Instant) and offered DLNA compatibility, the latter being a much-requested feature on the Roku.
Sony announced its latest streaming media box at CEDIA today, the SMP-N200, which adds 3D compatibility and live content streaming to the SMP-N100's already formidable features list. Additional details are scarce at the moment, so we'll have to wait to see what streaming services are being added to take advantage of live streaming and 3D support. The Sony SMP-N200 is slated to come out in October, but no price has been announced yet.
We haven't had any hands-on time with the SMP-N200, but our biggest knock on last year's SMP-N100 was its user interface. The SMP-N100 used a modified version of Sony's XMB interface, which we love on the PS3, but it doesn't work as well when you mostly want to navigate a single media type: streaming video. If the SMP-N200 offers an improved interface, we could see it being competitive with our current Editors' Choice, the Roku 2 XS.
