The next version of Lightroom should not only have better GPS support, but should be able to obtain data from GPX files. The plugin that I use allows Lightroom to read the GPX files from common hand held GPS units. This is a far easier method than to pick out each location from a map. While the map idea in Lightroom beta 4 is likely useful, I'm sure a lot of photographers use the popular and inexpensive GPS units when they go out and they would all appreciate the ease offered by the plugin to be built into the next version of Lightroom. Also, I believe that Aperture has this feature already.
