I wonder what specific uses they mean. It's kind of hard to believe those are "serious" use-cases, going beyond demonstrations done for marketing reasons... Then again, as soon as you have a serious use-case, you don't tell anyone about it, so it's really hard to evaluate how much (if at all) this stuff is really used in practice.
