I use mine mainly for netflix, I thought I may use it for airplay mirroring the ipad or using our MBP or MBA, but it doesn't really handle any high bandwidth stuff when using airplay. I think to really get all the benefits it brings, you'll want an iTunes media server, I just haven't gotten around to bringing one up. If you're just looking to play music off your iphone/ipad or stream from an itunes library sitting on a PC/Mac, then it works great.
