I haven't read the book yet (it's on my todo list, but I've been put off by some of the reported technical errors). I have heard that quote and I still stand by what I said. Even if that quote means what you're suggesting, it will take a long time to get from Jobs' idea to a final product. The iPad was developed before the iPhone, we see how that worked out. Not to mention, Jobs isn't running Apple anymore. Anything can happen. I wouldn't put too much stock in an idea mentioned in Jobs' bio and I certainly wouldn't make any purchasing decisions on it.
As for the patents, Apple has about a gazzillion patents that aren't always tied to shipping products, as do most tech companies.
I dunno, anything could happen, but I'd be very surprised if Apple released a giant display for people to replace their televisions with.
