No, Apple is just ahead of the game... you wouldn't want a digital tuner on an Apple device since that data isn't part of the web. And local storage isn't needed since it's already stored somewhere, so why duplicate the data?
Your ideas made since 15 years ago, but the web/internet has rendered those concepts obsolete... now "everything" is just a stream which is far easier to manage.
Could you stream me Avatar in BR quality, please? Apple might be ahead of the game but Apple fans clearly are not. By using iTunes they are still watching sub-DVD quality movies whilst the world moved on to BR quality.
