I use google earth for scouting and when I just want to get out of my office for a few minutes. It's a nice mental break to take a virtual walk on my hunting spots after not seeing the sun for 8 hours. As far as the terrain feature, it can be kind of hard to see the subtle dips and hills in the field, but if you turn the elevation exaggeration up to 3 (in tools --> options) you can see all the nuances very clearly. Also, the ruler feature is handy for measuring the distance between landmarks if you don't always have access to a range finder.
