Jason O’Grady doubles down on his prediction that Apple will today unveil two big-ass Macintosh high-definition television sets, running OS X on a dual-core Intel processor, complete with a massive hard drive, an iPod dock, bluetooth, wi-fi, and an Apple DVR system.

It’s a terrific pre-Macworld rumor, for two reasons. First, it’s ludicrous. Second, it seems, well, Steve-Jobs-ish. Think about it. Up to now, the merger of TVs and computers has been a geek hack – you have to bring a computer into your living room and plug your TV into it and deal with all sorts of ugly configuration hassles. Who needs it? Make them a single device, and the hassles go away. You get a TV-Tivo-Computer with an easy interface for managing your media and a direct line into Apple’s iTunes store for downloading video and tunes. You get the TV of the future.

Sure, it’s crazy. But so was the iPod.

UPDATE: At the last moment, O’Grady wusses out. If you can’t take the heat, get out of the reality distortion field.
