They charged me a bit, but I traded in the smoked Foretrex 101 for a 301. Nice machine. The manual is on a CD and you need a new copy Adobe reader to view it. I think its easier to use than the 101, but its still for computer geeks. It did come with a USB cable and I'm hoping to learn to do automatic route and waypoint entry from my computer since I like to use google earth and NG Topo. The waypoint mark and goto functions are button operated and don't require a lot of screen changes. It weighs 3.1 ounces with batteries and someone said it has more sensitive antennas but I can't confirm that, and I do not know about battery time.
