It's really only useful if you have Apple products, like iPads, iPods, Macbooks, etc.

I use mine everyday to AirPlay stuff off my Retina Macbook or iPad. $99 very well spent.

It's pretty cool to use off your iPad because you can airplay movies right off of it without connecting it. I use AVPlayerHD, which can directly play mkv, HD 1080p files, etc without converting. Then AVPlayerHD has an Airplay button so you can control it with the iPad, but it will beam the picture directly on the TV, so you don't have to convert to MP4, sync with iTunes, etc
