We have been convincing my father in law, who is in the construction business, to try the POS systems but he is having a hard time understanding the benefits that this could give him and us. We have been telling him that these gadgets would make his life at least 50% easier as they would do all the dirty work for him. But being a paper, old style guy, it would take a few more convincing powers before he could give us the go signal.
