Havent read that article, but my new ipad2 has certainly changed the way we handle visual media in my house. Massively changed the way.
All new DVDs (and a fair few old ones too. We've only a small collection) we now view via iPad the hdmi cable on our 32inch flat screen tv on the main room.
We can all now easily view and browse the web using this same method.
The BBC Iplayer, via the ipad2 and hdmi cable is now nearly a main stay interface on our tv these days.
Catchup tv also allows us live tv or all the major channels.
Great for listening to radio or music collection on iPad via the tv's sound system.
So yes, for us the ipad2 and mirroring capabilities has been a recent life changing revelation for us.
