Shown at CES is the Netgear Push2TV (PTV1000) which is a reciever which when used with Intel Wireless HD Display is the first step on the road to easily connecting the laptop to the lounge TV. Converts all signals to 720p and is unencrypted and no HDCP at the moment; hopefully that will come in a future version. Laptop needs one of the new series of CPU's and some Intel software which I am unable to figure out it it will be available seperately or as part of a bundle with a laptop. More info here:
