The Gadget: Linksys' slightly fancier Windows Media Center Extender, which streams the Windows Vista/XP Media Center interface over the network so you can watch live or recorded TV and downloaded files on TV in HD.
The Price: $299
The Performance: Fantastic. We were able to stream live 1080i over-the-air (OTA) HDTV with no glitches for the most part, and whatever glitches we did see were due to the fact that OTA reception in our area isn't great and we had a small antenna. But when we watched pre-recorded content in both 720p and 1080p, there were zero glitches or dropouts. We tested this both with the wired internet and the Wireless 802.11N network via Linksys's WRT600N Router, and it was super smooth even over Wi-Fi.
