I'd love one around home.... love my 305 and I'm sure I would enjoy an 800 even more for local training rides. As for touring, if i was really worried about getting lost I would just pull out my phone with built in Gps to get me unlost.... then back to the map. I've been very lost in the past while on longer tours. Wish I'd had something to confirm my feeling of being lost when in fact I was.... This was before I had a phone with this ability. Plus, having to worry about one more thing to keep charged would just not be worth it to me.
