No one will pay $2000 for a 55" Television. Period.
Apple shifted the industry from $0-$100 phones to $300-$900 phones because it brought something totally different to the table. Cell phones were prohibitively expensive in the 80's and over time declined to mainstream affordable prices, to even free. Apple put value on the phone again, something people were willing to pay for.
They set the new average price for a smartphone and the competition adjusted to it.
HD TV's used to cost $2,000 to $4,000 but the price steadily declined. You can get a tv for as little as $200 these days. The pattern is the same. An average of $799 will get you a 47-55" TV today. I would pay $1,599 (double) for an Apple TV with its design qualities and ease of use if Apple were able to reinvent the television like they did with music, phones and computers.
People spend way over $1,600 on Apple's computers all the time. Why wouldn't they be willing to invest the same on a TV which has a longer life span?
