I can't imagine anyone really needing a continually synchronizing clock. But
need is never a reason not to buy something cool.

I should know... in the past year, I've bought three of those clocks myself.
Why? Why not? It's cool to listen to WWV on one of my radios and watch my
clocks tick exactly in sync with the radio. It's kind of like my clock make
the radio beep.

A true gadget freak can NEVER have enough gadgets.
