The Gadget: The Kanex Mini DisplayPort and USB audio to HDMI adapter, which one-ups the previous Monoprice adaptor because there's audio.
The Price: $US40
The Verdict: It works. IT WORKS! Playing back 1080p trailers in Quicktime, powered by a MacBook Pro, on our plasma TV was fantastic. And the part where it actually has audio? Yes please.
It's quite easy to use. The USB and Mini DisplayPort goes into the MacBook Pro (or Mac Mini), and the other end takes an HDMI cable. Your Mac should automatically detect the new display, but you have to manually switch the audio output to the USB audio device. If you're planning on using a new Mac Mini, this is the way to go. The video quality is pretty much what you'd expect from a clean 1080p source, and those trailers look good.
And with the problems Apple's own Mini DisplayPort to DVI adapters are having, using this and an HDMI-capable monitor might be a smart idea.
The adapters will be available later in the week. I suggest you pick one up if you have any kind of Mini DisplayPort-capable computer you want to throw up onto your TV once in a while. Also, Monoprice has a unit coming up soon as well that's pretty similar. [Kanexlive]
