WiDi 2.0, as they are calling it, will work a lot like the original version we like so much and allows you to extend your desktop to an HD monitor, but unfortunately, it will require a new HDTVreceiver to enable the full HD capability and it still has that two second lag.
On the higher end is the updated YSP-4100, above, a rather tall but only 9cm deep soundbar with the receiver integrated that can be mounted on the wall right beneath your giant HDTV and then paired with a selection of wireless transmitters for iPods and the like.
