One place where Apple really exceeds is integration, everything they make integrates very well together.
If you have ever tried to setup a NAS drive for home server integration, you soon realize how horrible most backup and fileshare software is. Then hook up an Airport and wallah! Every Apple product, Iphone, Ipad, Itouch, Mac, and any non-mac product running Airplay gets a little pop-up saying your are connected. Now with no setup you can play any video, picture, movie you want from any of the above mentioned items on your TV.
As much as I hate to say it, no Windows or Linux integration can't even come close to that.
