I use it quite a bit.

For our property in WV, the boundaries are all off by about 100 yards to the south. Not that big of a deal as we all know where our property lines are, but since they just designated a chunk of paper company land that borders ours as "public" we forsee that we might run into problems with folks who follow the software over the tree markings and posted signs.

But as far as ease of use and the ability to use it "offline", it is great.
