Garmin is reportedly coming out with a Colorado series of handheld gps units. The units will have the bells and whistles. Pre-load topographic maps are featured, along with the ability to display satellite photos. Along with this is the High Sensitivity receiver.
Competition is good and we will have to see what Garmin has come-up with. You can expect to pay a higher price for the units, but they maybe cheaper in the long run because you are not buying topo software to load on your new gps. You can expect to pay two to three hundred dollars more for the new unit.
This may push them ahead of the DeLorme unit, which does not have a High Sensitivity receiver.
