Netgear Push2TV PTV2000

Supports 1080p video playback. Wall-mountable. Small and doesn't take up too much space. Backwards compatible with first generation WiDi (minus the improvements). Can stream protected content with driver updates to wireless chip and WiDi 2.0.

There is some latency. A bit pricey for an accessory.

For early adopters who appreciate streaming protected and unprotected video, photo slideshows, and music and want to do it wirelessly from their laptop, the Netgear Push2TV HD (PTV2000) is the most seamless way to do it.
