Alot of people have posted on my different threads about this topic with surprisingly little insight or thought in their comments. You're essentially slapping Apple in the face if you really think they'd get into the LCD market with ONLY televisions.
Apply this concept to the rumors and results for any of the other products Apple has released in the last 10 years. When the iPod came out there were other mediocre MP3 Players on the market, and if you applied the same logic, you would say "there are other products in this niche and Apple doesnt need to venture into this area." Or look at the phone market (yes I know its been referenced in this and other threads quite a bit). If you used the same logic with the iPhone, it would have made no sense for Apple to enter the television market.
Apple is an innovator. They see existing markets and create products that drive their own sales because they have things that other products cannot offer. If Apple were to enter the television market, their television would not only include AppleTV, but a fully integrated OS, possibly touchscreen just to up the ante, a premium sound system, and a seamless integration with ALL of apple's other devices, perhaps automatically when you came in range.
Now that would be a big step, so a smaller step would be to include AppleTV in their Cinema Displays, and do alot of their development and testing there before really entering the TV market. Just imagine 5 or 6 years from now if there was a PREMIUM, integrated TV from Apple. What do you think the product development path would have looked like to get to that end result?
Apple is famous for creating products that somehow make your life easier with incredibly complicated products (yes thats a compliment). That is much more of an art than the "im going to make a flat screen and dump it in a best buy" type of logic path.
If you're all Apple fans who frequently post on forums such as this, give Apple more credit than you're giving them, and when a question is asked, dont act impulsively; really think about it before dumping a paragraph of incoherent rambles that are relatively pointless.
Cheers.
