I still maintain that Apple has no cause to get into the very saturated television market. There's no way Apple can compete with existing sets pricewise, plus there's nothing they can do with their own brand television that they couldn't do with an add-on box like the AppleTV.
What about screen size? Are they going to have different options for different needs? We know how Apple has been historically about options, and you can't enter the television market with just one or two sizes available and expect to make everyone happy.
Even the hardcore Apple fans I know aren't going to run out and replace their televisions just because Apple starts making one, I don't care what "killer feature" it has. The TVs in my house are all doing the jobs they're intended to, and I'll only replace one when that changes. Not before.
I firmly believe that if Apple starts selling a television, it's going to be one of their occasional duds. I'm sure the tech will be impressive, I just don't think they're going to be selling them by the truckload like they're used to doing with iPhones and iPads. An Apple Television just doesn't make sense. I just don't think Apple can make any money off of it.
