I already use my iPhone and iPad as remotes with AirPlay it's absurdly simple to flip video onto any screen in my house or office.
This.
My Mom screams every time the cable bill comes in, "This shits way too expensive, I'm going to cancel it!!! Shit, then I won't get my shows, damn cable." After months of her whining about this I took her down to the Apple store, I was going to get her a Mac Mini and set it up as an HTPC with a wireless keyboard / mouse. She wanted the opinion of the sales guy as well and once she explained what it was he scrunches up his face in thought and says, "Come with me."
Walks us over the to Apple TVs, I wasn't too interested in that since I'd dismissed it as a physical front end for the iTunes movie store and other than Netflix (which the Blu-Ray player already did) I didn't see much use in it. So then he grabs his iPad and with a push of the button he's got AirPlay mirroring running and playing a movie right off the iPad on the TV, I don't know why I didn't think of it before! Once my Mom saw she could get her shows, she used his iPad to confirm all the channels she watches have apps that carry her shows, *and* have a connected device that she can keep in touch with the Grandkids via FaceTime and also fits in her purse, well, she was tickled pink.
She's set aside some cash for the iPad 3 and Apple TV 3 once they get released in March*, the Cable is getting cancelled not much later. :-)
* Rumours are sketchy on the Apple TV 3 is being released in March but with other rumours that Apple has been asking content providers to send them 1080p files, and the iPad 3 screen rumoured to be 1080p, it makes sense for it be released at around the same time.
