mikel has been experimenting with getting openstreetmap data on a Garmin handeld GPS. This is a massive step forward and points to all sorts of uses.
Also, the map of Weybridge made with XSLT and SVG described previously has made it on to the Weybridge wikipedia article! So, what a milestone! OSM maps have made it back to the mothership and been judged worthy to go on a wikipedia page.
