As promised, here is page 12 of the amazing 1979 book Future Cities: Homes and Living into the 21st Century.
My favorite aspect of this page is that not only are they speculating the coming of the radio-telephone wristwatch, they're speculating its nickname. The "risto" may not be a common sight today but I really wish my cell phone had "pop-out aerials."
Also, check out the "instant voting" they anticipate one could do through their "risto." I certainly forsee no problems with that. Electronic voting machines are pretty widely accepted as reliable in 2007, right?
Stay tuned, this book is over 30 pages of paleo-future goodness.
