This saved our lives. My husband and I take part in exhibitions. We started using I-Pad to process payments. It's perfect. It rotates left/right and back/forward. I put my hand on the back of an iPad when customers are signing credit card transactions, just like that. There's really no reason, I just do it. Some people press really hard while writing and I just don't want to risk the text falling backwards. You can place the I-Pad vertically or horizontally. We love it.
