Urban Outfitters has had them in the window for a while, and EB at the maul has them too... thinkgeek had them *last* xmas, IIRC. But yeah, it's a great concrete representation of moore's law, except that it still undershoots the curve :-)

It's also a reminder that "small" is not the lower-bound size limit, "elsewhere" is. A phone shrinking to just an earbud, for example. "The use case for a wristwatch isn't about optimizing wrist mounting - it's about knowing what time it is".
