I found something pretty cool at gizmag. Who would have thought that good old Dick Tracy (75 years now) was such a future men?! I mean the comic was ok, not my favorite and the soundtrack from Madonna was one of their best (the only LP I own from her.. ;-) but that.. I should read them again with a different view:

Dick was using Electronic Telephone Number Pickup in 1954, 28 years before Caller ID was patented. One we've still to see was the Magnetic Space Coupe which took Tracy to the moon in 1962, seven years before the first actual moon landing, with the prospects of the magnetic car still realistic, having been used in the Lexus Concept from "Minority Report". The most iconic of Dick Tracy's kit though, was his wrist communicator, a device that started countless millions of technological dreams in a young American technology community which went on to create ubiquitous wireless communication.
