Back in late December, I mentioned that a company called HEX had a cool silicone watchband in several colors that would turn your new iPod nano into a watch. The only downside to that is that geeks that like to use their nano for working out with the NIKE+ accessory couldn't use the HEX band. HEX has announced that in April it will have a new version of its cool watchband.
The new version of the watchband is called the Sport Watch Band and it is fully compatible with the NIKE+ accessory. The change for compatibility appears to be nothing more than cutting the side out of the case so the little dongle for recording your workout parameters can be installed. I would think if you already own a HEX watchband a sharp knife and a steady hand could mod yours to work with NIKE+ too.
HEX also has a new armband that you wear around one of your guns to hold the cable in place so it doesn't flop around on you while you run. Having cables bouncing on your arm as you workout is irritating after a while. The silicone of the watchband also projects the nano while you work out. Pricing is unannounced at this time, but it should be very close to the $30 the original cost.
