I really don't have a whole lot that I can add to this thread. I don't use my GPS when driving unless I'm out in the middle of nowhere and I need to find my way back. I use it a lot when I'm mountain biking but again I don't ever look at it, it just sits in my camelback until I get home and then I use it for ride analysis. I'm really impressed with the 60csx and if i had my druthers that's what I would be packing around, but since my eXplorist only cost me $30 you won't find me complaining. The only thing I've got to say that is even remotely helpful is that you should check out TopoFusion, it's dirt cheap and for mapping biking and hiking I think it's fantastic. There is a full functioning demo that has no expiration, check it out.
