Who would have thought… This is kind of interesting and something I have never though of Tablet PC’s being used in the past. I use Tablet PC’s daily to do mapping, but most of what I do is above ground, or mapping boring holes. These guys are talking about Tablet PC’s being taken underground to map out caves. One of the guys is even using this Tablet PC pictured on the right as his under ground mapping tool. Oh, and there is kind of a heated debate going on as well.
