I appreciate the ideas - out in the field now, so will be a little slow to digest them and get back to reporting on what works. Its pretty amazing how many dirt roads end on the topo maps, yet I just keep on driving... This is why satellite images are so much better for finding access. My gut feeling says I will end up with a windows machine for the work, but the tablet is fast, plus the battery lasts so long. Not sure about loading a serious amount of sat. images though.
