There has been some buzz on the blogs about the possibility of smart phones replacing more standard recreational grade GPS devices. This article in the NY Times suggests that the smartphone is beginning to displace the GPS receiver as a convenient way for drivers to get directions to unknown destinations.

Next might be the use of smart phones for non-driving uses of the recreational GPS devices, like geocaching, or science education.  We will be releasing our OakMapper device for the iPhone in September, and will likely be better able to comment on the comparison.
