Here's a quick comparison between the iPulse, SD Card, and latest gen iPod Nano with sizeeasy: http://sizeasy.com/page/size_comparison/31203-inPulse-vs-iPod-Nano-vs-SD-Card http://sizeasy.com/page/size_comparison/31203-inPulse-vs-iPo... Only the watch body itself is shown: SizeEasy only supports cubic dimensions, so I couldn't find a way to show the wrist band. Also, SizeEasy requires all three dimensions be provided, and since I couldn't find official dimensions anywhere else I used those cited around the web, for example: http://www.berryscoop.com/2009/11/questions-answered-about-the-inpulse-watch-for-blackberry/ http://www.berryscoop.com/2009/11/questions-answered-about-t... Overall, decently sized but definitely not head-and-shoulders above the Nano.
