Unsurprisingly we've confiscated the keys to the Newsletter from MaFt and he won't be allowed near the computer until he apologises. We took bets on how many complaints we'd receive in response to his April 1st Newsletter spoof as, whenever we've done something in the past, we've had a dozen or so very strongly worded emails from people who seem to have had the humour gene extracted at birth. I'm delighted to report that everyone who did get in touch this time did so in good humour and we all lost the bet.

Lots of places have a radio signal that can set watches, and the GPW-1000 will use these by default. But if the radio signal isn't available then it switches to GPS to set the current time.

Is this technology for the technology's sake?
