Well, I do have an Apple TV connected to my Beovision 10. Main reason is that I now have all my music accessible from the TV screen, playing through my wonderful B&O speakers. Before I always had to turn on my computer, which on the one hand is not so nice, and on the other hand has a lower WAF (Wife Acceptance Factor).
I also like the capability to rent a move every now and then, without having to leave home. Very convenient!
I never intended to use the AppleTV as a DVR replacement - my cable box has a bultin 500 GB hard disk, can record HDTV, and is perfectly controllable through my Beo 4.
Any questions? Feel free to ask.
