Apple do devices
Apple's forte is in devices. If they want to dominate the home TV space, then they need to work on a TV that is so fine, that it does everything we would like it to do, and more, and that we would want one.
This is setting the bar quite high but Apple has answered such a challenge in the past.
I'm still of the opinion that Apple should go into the games market. They should have just about enough to buy a controlling share of EA. With such a control they could ensure that all games were first released for Apple devices and that games optimised accordingly to give Apple devices an unfair advantage. There may even be an anti-trust suit as a consequence.
