This adaptor is absolutely brilliant! With it you can effortlessly connect your Mac (one with a Mini Displayport) to your widescreen TV or home entertainment system. And, unlike other solutions, sends video AND audio through the one HDMI cable (not supplied). I have already used it to view BBC iPlayer HD content on my Sony widescreen TV and the video and audio playback is stunning. You could also view your iTunes video library. If you have an iPhone or iPod Touch you can then remotely control iTunes with Apple's Remote app. Or watch YouTube videos, your slideshows ...
I must also commend Neet on their speed of delivery and the excellence of their technical support - replying to an emailed set-up query within an hour on a Saturday!

I am already convinced that this is the one MUST HAVE accessory for any MacBook Pro owner!
