The way I see it, sales aren't brilliant so something needs to change, probably at Macworld. I'm personally waiting for Apple to include a Digital TV tuner (called Freeview here in the UK - using DVB-T). And a HD-DVD or Blu Ray player. Then I will buy one for every room in the house. What i don't want is a TV remote, DVD player remote, freeview/hard disc-recorder remote and an Apple TV remote. I want my Apple TV to be my TV, TV recorder, photo album, duke box and movie collection.
Software wise, A link to the (hopefully) new movie rental store is a MUST.
