Wrist-mounted iPod nano not quite the running companion of which you'd originally dreamed? This Nike+ SportsWatch GPS will be happy to take its place. We spotted the TomTom-branded fitness watch at CES this year, and now it's formally on sale -- though unfortunately for a price far steeper than those of its immediateancestors. Of course, the $199 band isn't just a replacement for the Nike+ iPod system, it also uses that onboard GPS to keep track of where you run, much like the Nike+ GPS app but without the necessity for an iPhone 4 bouncing around your person. Did we mention it's also a watch?
