The History of PDAs in Words and Pictures
evanak writes "For the past four years, I've been studying the history of PDAs. It's all summarized in a 10,000-word article on my web site." This history is also illustrated with some pictures and photographs, which are worth it all by themselves.
There are six words missing from this 10,000 word essay; "The Hitchhiker's Guide to the Galaxy".
It featured hypertext, multimedia content objects, a wiki-like browsing interface and of course collaborative document editing (which sounds bad but was mostly harmless).
Sturdy, rugged, built to take all kinds of knocks, apparently easily recharged despite country (or planet, for that matter) and quite affordable. All pre-1980.

So not only did this guy give birth to the idea of PDAs.. but also to the idea of patenting something general and sweepingly broad, and then suing later when somebody who isn't too lazy implements his idea... wonderful!
Don't anthropomorphize computers: they hate that.
