Not a great example of a wrong prediction, IMHO. People did never end up taking laptops fishing. Tablets, ebooks, and cell phones are fundamentally different things that address the key problems noted in the article (screens and keyboards).
The thing about predictions that gets ignored in retrospect is that there are always implicit qualifiers, because it's not very interesting to hypothesize about the totally unconstrained future.
