Man! Lot of negative stuff. I've only had my PN-20 for a very short time but I love it!
For me, it's about the maps. And the mapping capabilities on this puppy blows everything else I've seen out of the water.
I would admit that it can take a little getting used to, but well worth the education. I haven't experienced the refresh issue at all. I did have a problem importing my first couple of maps but that was (I think) because they were just too large. You know, Like the entire state of Oregon in one file/map.
I also admit that I am nowhere near as dedicated to this sport as some of you posting here, nor am I as experienced. I am also aware that honest opinions are important. I was just suprised to see these comments about something I had just gotten all giddy about.
Bottom line for me - I'm a DeLorme believer. For the first product out of the gate, I think they did great.
