The Tablet Prediction in the 1930s

I've run across a blog post mentioning Arthur C. Clarke predicting the iPad in the 1960s:

In 1964, legendary science fiction writer, inventor, and futurist Arthur C. Clarke predicted the future with astounding accuracy, presaging everything from telecommuting to the digital convergence.

I'm not trying to claim this as false. However, there is an earlier prediction on a similar device, by Vannevar Bush with his "Memex" concept. From the Wikipedia article:

Bush introduced the concept of what he called the memex (possibly derived from "memory extension") during the 1930s, which he imagined as a microfilm-based "device in which an individual stores all his books, records, and communications, and which is mechanized so that it may be consulted with exceeding speed and flexibility. It is an enlarged intimate supplement to his memory."

Which in turn, the "Memex" concept led to the "Hypertext" term coined by Ted Nelson, leading to what we know today as the Hypertext Transfer Protocol, or HTTP for short.

What is most interesting to me is that the prediction about the "enlarged intimate supplement to his memory" is actually true.
