I have a Transformer Infinity with the dock that I use as a netbook that I can plug into tvs and stream movies off of. The most recent iterations of the Nexus Q et al have mini usb and mini hdmi ports and can effectively do the same thing as well. Android devices have been at the point of being desktop replacements starting this year, and mainly due to the Transformer tablets, but any bluetooth keyboard + hdmi complient device can serve the same function given a beefy enough processor.
