A GPS for Genealogy

One of the things that i’ve found very useful about the GPS in the Nokia N900 is that when the wife and I are out investigating the back-and-beyonds the N900 is suppyling us with townlands as we traverse. In genealogy often the only locational information you can find are townlands, and many modern maps do not label them. Now I don’t know if othe GPS’s have this data, but it’s nice to have them in the pocket, in the form of the N900.
