Just received my Nike+SportsWatch GPS. A very neat and not too crazy looking watch. Might even wear it every day! Rated at 40 days of use in non GPS mode as unlike the Garmin 205 the clock mode is separate from run mode. Kit includes a Nike+ foot sensor. You can add sensors such as the Polar Heart Rate Wearlink.
Numbers are very clearly visible on the white on black LCD screen. There are only 3 buttons on the left side: a yellow select and scroll up and scroll down. I have not yet tried the tap function for laps.
A bit thicker than I expected but far less bulky and narrower than my Garmin 205. Very comfortable on the wrist as the antenna pod (below 34 in first picture and at top of the second picture) is far thinner and smaller than the Garmin.
Charging, updates and synch is via a USB cable or directly into your USB port (Mac or PC) . The male end of the standard size USB is built into the wrist clasp and folds out. I hope it is not to fragile or subject to corrosion. Here I am using the included male/female USB cable to synch and charge via my Mac.
More after a first run.
