Dual sent me over their latest GPSr, the XGPS150, for a test drive. This GPSr not only works plug and play for iOS, but can also be used with many other smart phones. The main benefit I see to this is that it adds GPS functionality to your iOS device that may otherwise not have a built in GPS, such as the iPod Touch or iPad (wifi only model). You can also use this with your device that may have a built in GPSr. Because the receiver has a built in battery, this helps save some of your device battery power that you would other wise use for the built in GPS chip.
