I have the new SageTV HD Theater in house. This is the updated HD capable extender device from SageTV.

 Pros:

• The interface is considerably more responsive than the previous model
• Smaller form factor
• Same great picture quality from HD sources such as a Hauppauge HD-PVR as the previous model
• USB ports afford access to external storage devices allowing access to media files stored on them
• Offers a full standalone media player mode allowing access to media stored on network devices and online services such as Hulu (Playon! required for sites like Hulu)

 Cons:

• Same remote as the previous model which means it is still a bit clunky
• There is no simple way to return to standalone player mode when in SageTV Extender mode
• No access to standalone player features while in SageTV Extender mode

 Other Info:

• Has two USB ports (one front, one rear)
• Has an optical digital audio output but no coax
• Video outputs include: HDMI (cable included), component, S-Video/Composite/Stereo Audio (cable included)
• Comes with a long Ethernet cable
• Uses a wall wart power adapter unlike the previous model
