Last week the old bear took the plunge and purchased an iPhone 4S (after owning a cellular phone that was, well, a phone).. It's smarter than I am and it's truly amazing in just how much "computer" is packed into such a small device.
It's SIRI feature immediately brought to mind the old BBC series Star Cops that started (and unfortunately, after nine episodes, ended) in 1987.
David Calder (the star) has a hand-held "assistant" - - aptly named "Box." You can find the first mention of Box at the 8:15 point in this video.
The series was set in 2027 ....... maybe we are getting closer.
