I just started reading The Master Switch over the weekend, and I think what the writer here is talking about is the potential to completely destroy the current PC industry, much in the way that the telephone destroyed telegrams. Whether it has or not won't be obvious until much later. I'm not hoping it has happened, nor do I necessarily believe it has. But I think 30 years from now we might be reading about how this was the defining moment in the death of PCs. This may be completely obvious to everyone here already, but it was a whole new line of thinking for me after reading a bit of that book.
