The DeLorme Earthmate PN-20, which continues to generate significant interest, has been delayed once again. First announced in early 2005, the PN-20 is now "scheduled to hit the market in late 2006." Why the interest in this oft-delayed, near mythical unit? It's slated to be the first consumer-level ruggedized handheld GPS that will accept raster imagery -- that means USGS topo maps, aerial photos and satellite imagery. But I'm betting that it's going to be limited to DeLorme's proprietary (and quite expensive) format -- Aerial Data Packets (ADP). I just hope I get to see one in my lifetime!
