This watch is really cool, but not incredibly practical.  The lack of screen and 1/16" headphone jack are it’s big problems, but it is nice to be able to keep music with you everywhere you go. The fact that it has a USB plug built-in means that you can use it as a thumb drive, and the ability to record audio is incredibly useful. All-in-all, its a really cool device, if you're willing to spend money on something that isn't incredibly practical.
