Actually the connectivity problem was 100% unsolved which is what lead to the end of the device. The supporting technology wasn't available unfortunately.
The basic idea of the NewsPAD was exactly the same though.
They decided to move into the cable/STB market after this as they could deliver the same experience with the connectivity that was already there. They did this successfully for a few years in the late 90's before they marketed themselves into a hole and gave up.
Apples innovations wasn't in "the basic idea", it was in lots of implementation details that make that basic idea into a usable product. If you don't see this, then there is no point in arguing further.
I could just as well say that there has happened exactly zero innovation in the cell phone industry in the last 30-40 years, since "the basic idea" was shown in a science fiction series in the 60s. By doing this, I would be ignoring all the inventions necessary to make that "basic idea" into a real product.
You are ignoring the inventions needed to make a finger-based multi-touch interface possible on a small device, and accurate enough to leave out a physical keyboard.
Sure, wireless makes them much more usable, but claiming this is the reason for its success is just as silly as saying laptops weren't successful before Wifi (hint: they were!).
Without cellular data the iPhone would still be a killer device just as a cell phone with a music and video player, and the iPad with a complete office suite and other apps.
Cellular data was widely available in 1996, at least in Europe. I know because I had a PCMCIA card connected to my cell phone at that time.
But of course, you can keep twisting facts to fit your theory all day long if you want, I know nothing I can say will change your opinion.
